Anaesthetising obese patients have – Peri‐operative management of the obese surgical patient 2015

Some obese patients died from complications of general anaesthesia whilst undergoing procedures that could have been performed under local or regional anaesthesia where only part of the patient's body is anaesthetised. The report estimates that a life-threatening airway complication occurs in less than one in 20, general anaesthetics 0.

Causes of obesity

Obstruction can occur due to collapse of airway muscles or if patientw anaesthetic breathing tube becomes displaced or blocked by secretions, blood or a 'foreign body'. These were not bad clinicians, just people who lacked insight into such situations and factors. When a patient is anaesthetised, the anaesthetist a specialised doctor keeps the airway passages open by inserting a tube there are various sorts into the airway. In some cases this alternative appeared not to be considered. The airway must remain open at all times or the patient will suffocate in a few minutes.

The report has several findings and recommendations; but those on obesity and the monitoring of breathing are among the most striking. A well equipped operating theatre and a professional, experienced and diligent have who possessed a perfect technical skill set were overtaken by an unanticipated emergency. The report has several findings and recommendations; but those on obesity and the monitoring of breathing are among the most striking. Obese patients have double the risk of airway problems during an anesthetic, study shows. This leads to swelling and may cause obstruction. Several authors and organisations have recommended that it should be used routinely in ICUs but, at present, this does not appear to be happening.

Dr Nick Woodall, Consultant Anaesthetist at the Norfolk and Norwich Hospital Norwich, UKand anaesthetising obese patients have author of the report says: "Our findings show that patients who are obese have twice the risk of major airway problems during anaesthesia, compared to non-obese patients. The report highlights that the Intensive Care Unit is the place where earlier detection of problems could save lives. Useful individual cases for journalists to refer to— Due to the confidential nature of the project is it is not possible to identify patients or families of patients affected by the airway complications reported to NAP4. When a patient is unconscious there is a tendency for the airway to collapse obstruct as the muscles keeling the airway open stop working. The report shows that in a small number of cases there is room for improvement and it is important that as a profession we listen to these lessons. Other findings The most frequent complication leading to death for an airway complication during anaesthesia was inhalation of stomach contents.

  • The obese obstetric patient is particularly at risk of VTE and conversely, postpartum haemorrhage. Regional anaesthesia is recommended as desirable but is often technically difficult and may be impossible to achieve.

  • Airway problems were more likely to result in death in patients sedated on ICUs than if they occurred during anaesthesia for surgery. Dr Nick Woodall, Consultant Anaesthetist at the Norfolk and Norwich Hospital Norwich, UKand an author of the report says: "Our findings show that patients who are obese have twice the risk of major airway problems during anaesthesia, compared to non-obese patients.

  • Dr Cook says: "Despite the finding of this project, it is clear that anaesthesia remains extremely safe.

  • Patient positioning is of paramount importance before induction, particularly head position.

The single most important change that would save lives is the use of a simple breathing monitor, which would have identified or prevented most of the events that were reported. The report rightly highlights the role of human factors such as judgement, communication, equipment standardisation and systemic issues as critical factors in moving the fine line between success and failure. Dr Ellen O'Sullivan, President of the Difficult Airway Society, adds: "The Difficult Airway Society welcomes the publication of this important study which emphasises the critical importance of high quality airway management in providing safe care of patients during anaesthesia and in intensive care. The project, which identified that 2. Guidelines to cope with such problems were not followed; but apparently neither were the team rehearsed in such guidelines.

The exclusion of obese patients from the advantages that day surgery may offer should not be made on the basis anaesthetising obese patients have weight alone. Anaesthrtising mobilisation is vital and most patients should be out of bed on the day of surgery. Medicines and Healthcare products Regulatory Agency. Prophylaxis against VTE is vitally important for the morbidly obese patient in critical care and should follow the guidelines given above. British Journal of Anaesthesia ; : 26—

Circulation ; : — Bariatric operating table, able to incorporate armboards and table extensions, attachments for positioning such as leg supports for the lithotomy position, and shoulder and foot supports.

Comorbidity

Laparoscopic adjustable gastric banding is a recognised treatment for obesity. Exercise ECG testing may be impracticable, but even a short walk along the ward or an attempt at climbing a flight of stairs can give useful functional information. The report has several findings and recommendations; but those on obesity and the monitoring of breathing are among the most striking. There is an increased risk of operative and postoperative complications, including increased rates of postpartum haemorrhage, prolonged operative times, and infective complications such as endometritis and wound infection

Since the work of spontaneous breathing is increased in the obese patient, tracheal intubation with controlled ventilation is the airway management technique of choice. Many of the formulae for calculating lean body weight are complex but one of the most widely used is that of Janmahasatian et al. Nutrition in Clinical Practice ; 29 : — If pneumoperitoneum is used, remember that it causes a significant decrease in static respiratory system compliance and an increase in inspiratory resistance though little increase in a —a gradient ; ventilatory variables must be adjusted accordingly, and PEEP is desirable to maintain oxygenation during controlled ventilation. Surgery for Obesity and Related Diseases ; 4 : S56— There is a high incidence of gastro-oesophageal reflux and hiatus hernia. For mechanical ventilation, ideal body weight is used to calculate the initial recommended tidal volume of 5—7 ml.

In addition, obese patients were more likely to die if they sustained airway complications anaesthetising obese patients have ICU. Patients are still left to come around in their own time following withdrawal of Dr Peter Nightingale, President of the RCoA, comments: "I believe this report highlights areas of critical concern for all doctors involved in maintaining the airway of patients receiving anaesthetics or in intensive care units. Airway problems were more likely to result in death in patients sedated on ICUs than if they occurred during anaesthesia for surgery. These are collectively termed 'human factors'. Note: Content may be edited for style and length.

  • Thrombosis Obesity is a prothrombotic state and is associated with increased morbidity and mortality from thrombotic disorders such as myocardial infarction, stroke and VTE

  • We hope our findings will encourage anaesthetists to recognise these risks and choose anaesthetic techniques with a lower risk, such as a regional anaesthesia, where possible, and also prepare for airway difficulties when anaesthetising obese patients.

  • However, as its clearance is increased in obesity, clinicians should give consideration to increasing the frequency of dosing where analgesia is problematic.

  • Introduction of capnography to more ICUs would require modest cost and would require training of nurses and those doctors who are not familiar with its use.

Features of the metabolic syndrome should be actively identified as there is a strong association with cardiac morbidity Anesthesia and Analgesia. An important patients have note is that patients with gastric bands in situ who present with sudden onset of dysphagia or upper abdominal pain should be considered as having a band slippage until proved otherwise. Regional anaesthesia Where possible, regional anaesthesia is preferred to general anaesthesia, although a plan for airway management is still mandatory Maternal obesity and risk of preterm delivery.

In addition, obese patients were more likely to die if they sustained airway complications in ICU. Martin Bromiley family.

Woodall, C. The airway anaesthftising be injured by anaesthetic or anaesthetising obese patients have procedures or by a disease process. Amaesthetising a patient is anaesthetised, the anaesthetist a specialised doctor keeps the airway passages open by inserting a tube there are various sorts into the airway. Airway problems were more likely to result in death in patients sedated on ICUs than if they occurred during anaesthesia for surgery. Elaine's case highlights that even when the risk factors are relatively low, clinicians can find themselves dealing with an unanticipated emergency which can overtake even the best people if they are not mentally prepared and trained to deal with the various human factors that can lead to disaster. Greater use of this device will save lives. The single most important change that would save lives is the use of a simple breathing monitor, which would have identified or prevented most of the events that were reported.

The airway must remain open at all times or the patient will suffocate in a few minutes. The report makes several recommendations to improve the safety of airway management in the ICU. Several authors and organisations have recommended that it should be used routinely in ICUs but, at present, this does not appear to be happening.

  • However, with increasing weight, body surface area increases and hence absolute basal metabolic rate values are higher than in lean individuals. Airway problems were more likely to result in death in patients sedated on ICUs than if they occurred during anaesthesia for surgery.

  • Dr Tim Cook, a Consultant in Anaesthesia and Intensive Care at the Royal United Hospital, Bath Bath, UKand one of the report authors, says: "The findings of this report indicate that when airway problems arise in this group of sick patients the consequences are often very severe.

  • Cardiovascular system Obesity leads to increased blood pressure, cardiac output and cardiac workload.

If the airway becomes havw obstructed at any level the passage of oxygen into the lungs and carbon dioxide out cannot occur. The Capnograph breathing monitor When we breathe out we exhale carbon dioxide a waste product. In the very obese this risk is even higher. Airway complications Major airway complications usually fall into one of three categories i Obstruction. The report highlights that the Intensive Care Unit is the place where earlier detection of problems could save lives. It studied only events serious enough to lead to death, brain damage, ICU admission or urgent insertion of a breathing tube in the front of the neck. We recommend that a capnograph is used for all patients receiving help with breathing on ICU; current evidence suggests it is used for only a quarter of such patients.

A multimodal analgesic approach is often anaesthetising obese patients. An enhanced recovery protocol is essential Suggested initial dosing scalars for commonly used anaesthetic drugs for healthy obese adults notwithstanding the fact that titration to a suitable endpoint may be necessary. Chest X-ray may be used to assess cardiothoracic ratio and evidence of cardiac failure. There are a number of terms used to describe the weight of a patient; the four most useful are shown in Table 2. Mechanisms of thrombosis in obesity. Before discharge from the PACU, all obese patients should be observed whilst unstimulated for signs of hypoventilation, specifically episodes of apnoea or hypopnoea with associated oxygen desaturation, which will warrant an extended period of monitoring in the PACU.

In addition, obese patients were more likely to die if they sustained airway complications in ICU. Journal British Journal of Anaesthesia. A major UK study on complications of anaesthesia has shown that obese patients are twice as likely to develop serious airway problems during a general anaesthetic than non-obese patients. Most patients who had complications that were reported to this project had identifiable risk factors such as obesity or head and neck cancer; these patients are at a much higher risk of airway complications than healthy patients undergoing anaesthesia and surgery. Since the death of my late wife the anaesthetic community have worked hard to learn the lessons that are inevitable in such a tragic case.

Anaesthetisjng, due to increased plasma cholinesterase activity, total body weight is appropriate for suxamethonium. Drug dosing There is limited information on the effect of obesity on the pharmacology of commonly used anaesthetic drugs. EDA seems particularly attractive in obese patients undergoing major abdominal surgery, although the superiority of EDA in obese patients is not yet proven. Enteral absorption of drugs is not altered in the morbidly obese. Where the patient is nursed after operation depends on the nature and extent of the surgery and on the individual patient.

T ired Do you often feel tired, fatigued or sleepy during the daytime? Extra time should be allowed for positioning the obese patient and performing anaesthesia. Arterial blood gas analysis may be useful in those suspected of respiratory comorbidity OSA, obesity hypoventilation syndrome, large collar size, and other pulmonary disease as the patient's habitual values provide a useful guide to weaning from ventilation and the potential need for extended perioperative respiratory support.

With induction agents, a dose based on total body weight will last longer than one calculated using lean or adjusted body weight but is likely to result in significant hypotension. Nightingale1 M. Duckitt K, Harrington D. It is recommended that a single person in the anaesthetic department be nominated as the obesity lead. However, less fat-soluble drugs show little or no change in volume of distribution e. In combination with an increased blood volume, this leads to an increased risk of heart failure.

Hve function tests may reveal a restrictive defect, but are not performed on all patients. Patients should have return of their airway reflexes and be breathing with good tidal volumes before tracheal extubation, which should be performed with the patient awake and in the sitting position.

Doses of neostigmine and sugammadex are related to the timing and total dose of neuromuscular anassthetising drugs to be anaesthetising obese patients have and can usually be titrated to effect. Systemic hypertension is 10 times more prevalent in obesity. This article has been cited by other articles in PMC. There may be an advantage in estimating lean and adjusted body weight and recording these in the patient's records to aid the calculation of drug doses.

Despite the potential reduction have neuraxial volume due to adipose tissue, standard doses of local anaesthetic are recommended for central neuraxial blockade Subarachnoid block with an opioid adjunct is a useful technique resulting in reduced postoperative opioid requirements. Respiratory medication prescriptions before and after bariatric surgery. The obese patient is more at risk from arrhythmias because of: myocardial hypertrophy and hypoxaemia; hypokalaemia from diuretic therapy; coronary artery disease; increased circulating catecholamines; OSA sinus tachycardia and bradycardia ; and fatty infiltration of the conducting and pacing systems.

When a patient is anaesthetised, the anaesthetist a specialised doctor keeps the airway passages open by inserting a tube there are various sorts into the airway. The report shows that in a small number of cases there is room for improvement and it is important that as a profession we listen to these lessons. Neither case was part of the NAP4 project.

Current advice is not to deflate the band before surgery; however, depending on the extent and type of surgery, a decision to diet the band may be made on an individual basis. Day Case Surgery. This may be needed for several nights after operation, as OSA occurs during deep sleep and rapid eye movement sleep, both of which may be suppressed in the immediate postoperative period and show rebound several nights later. This combination means that, following the cessation of breathing, arterial oxygen levels decrease rapidly. Less well known is the obesity-hypoventilation syndrome.

Prevalence and clinical outcome of hyperglycemia in the perioperative period in noncardiac surgery. For opioids, the clinical effect is poorly related to have plasma concentration The answer to this question is not simple.

Before discharge anaesthetising obese patients have the PACU, all obese patients should be observed whilst unstimulated for signs of hypoventilation, specifically episodes of apnoea or hypopnoea with associated oxygen desaturation, which will warrant an extended period of monitoring in the PACU. Dose adjustment of anaesthetics in the morbidly obese. The patient's weight excluding fat.

Patients have intra-arterial monitoring should be considered for situations where rapid haemodynamic patient are possible, surgery is prolonged, in patients with cardiorespiratory disease or if non-invasive arterial pressure monitoring is impractical. A multimodal analgesic approach is often required. However, patients who have obesity-related comorbidities carry a dramatically greater risk of perioperative complications.

Guidelines to cope with such problems were not followed; but hzve neither were the team rehearsed in such guidelines. The report provides a specific insight anaesthetising obese patients have the high risks and complications associated with airway management and obese patients which should act as a focus for all healthcare professionals treating such patients. Cook, N. There were apparent failings in situation awareness, leadership, judgement and team working; as well as confusion over the use of equipment. The report is important for patients and anaesthetists alike. These were not bad clinicians, just people who lacked insight into such situations and factors.

Since the death of my late wife the anaesthetic community have worked hard to learn the lessons that are inevitable in such a tragic case. Journal References : T. The report has several findings and recommendations; but those on obesity and the monitoring of breathing are among the most striking. Monitoring breathing in intensive care units Airway problems were more likely to result in death in patients sedated on ICUs than if they occurred during anaesthesia for surgery. Several authors and organisations have recommended that it should be used routinely in ICUs but, at present, this does not appear to be happening. Dr Ellen O'Sullivan, President of the Difficult Airway Society, adds: "The Difficult Airway Society welcomes the publication of this important study which emphasises the critical importance of high quality airway management in providing safe care of patients during anaesthesia and in intensive care.

The report makes several recommendations to improve the safety of airway management in the ICU. When a capnograph detects carbon dioxide it indicates breath by breath that the patient is breathing through a clear airway and that, if the patient has a breathing tube, this is not displaced or blocked. The capnograph can therefore be used to detect problems with the airway as soon as they occur. Elaine Bromiley In April Elaine Bromiley died after there was difficulty in managing her airway after she was anaesthetised for routine nasal surgery. We hope our findings will encourage anaesthetists to recognise these risks and choose anaesthetic techniques with a lower risk, such as a regional anaesthesia, where possible, and also prepare for airway difficulties when anaesthetising obese patients. In some cases this alternative appeared not to be considered.

The prevalence of morbid obesity is increasing in the UK. Obesity Reviews ; 8 : — Table 1 World Health Organization classification of obesity 4.

  • It is strongly recommended that additional induction agent be given if there is a delay in commencing effective maintenance anaesthesia after induction. In addition, obese patients were more likely to die if they sustained airway complications in ICU.

  • Some patients have a hole havd in the front of their neck tracheostomy and a tube placed directly into the trachea tracheostomy tube. We recommend that a capnograph is used for all patients receiving help with breathing on ICU; current evidence suggests it is used for only a quarter of such patients.

  • Planning postoperative care The planned postoperative management of most obese patients should resemble the enhanced recovery programmes of many surgical specialities. Therefore, any obese patient undergoing major surgery, or those with a history of comorbidities, should be nursed in an appropriate level 2 or level 3 facility.

  • A robust airway strategy must be planned and discussed, as desaturation occurs quickly in the obese patient and airway management can be difficult. Standard doses of adrenaline and amiodarone should be used.

  • Guidelines to cope with such problems were not followed; but apparently neither were the team rehearsed in such guidelines.

  • It is my sincere hope the NAP 4 hace follow-on work will enable a broader clinical community to make disaster much less common and heroic saves much less needed. Most patients who had complications that were reported to this project had identifiable risk factors such as obesity or head and neck cancer; these patients are at a much higher risk of airway complications than healthy patients undergoing anaesthesia and surgery.

Cook, N. The report estimates that a life-threatening airway complication occurs in less than one in 20, general anaesthetics 0. Woodall, J. This is a well recognised problem and in the vast majority of anaesthetics this is prevented, however in some reported cases the appropriate preventative measures were not taken. Several authors and organisations have recommended that it should be used routinely in ICUs but, at present, this does not appear to be happening. Oxford University Press.

  • Adverse events occurred more frequently in obese patients when anaesthetised by inexperienced staff.

  • However there have been two cases of such events that have been prominent and are in the public domain.

Email chrisfrerk btinternet. In some cases this alternative appeared not to be considered. Other findings The most frequent complication leading to death for an airway complication during anaesthesia was inhalation of stomach contents. Obese patients have double the risk of airway problems during an anesthetic, study shows. These passages enable oxygen in air to enter the lungs and carbon dioxide to leave the body.

Although the poor physical condition of patients needing to be in ICU possibly accounted for some the difference in outcome, the report identified several other patients have. If longer acting opioids e. Sign In. Generally, obese children experience fewer medical complications than obese adults, although derangements of respiratory physiology are common across all age groups. Central obesity and metabolic syndrome should be identified as risk factors. This is in part due to higher cardiac output and splanchnic blood flow.

Dr Peter Nightingale, Anaesthetising obese patients have of the RCoA, comments: "I believe this report highlights areas of critical concern for all doctors involved in maintaining the airway of patients receiving anaesthetics or in intensive care units. Physician anesthesiologists work with your surgical team to evaluate, monitor, and supervise your care before, during, and after surgery—delivering anesthesia, leading the Anesthesia Care Team, and ensuring your optimal safety. An exception to this is succinylcholine, which should be dosed to total body weight. An increase in Vd prolongs the elimination half-life, despite increased clearance Table 3.

Royal College of Obstetricians and Gynaecologists. Obese patients are at increased risk of venous thromboembolism; appropriately sized compression stockings, low molecular anaestetising heparin, and dynamic flow boots should be used from arrival in theatre until full postoperative mobilization. Pulmonary function tests may reveal a restrictive defect, but are not performed on all patients. However, there is some evidence suggesting that hypocaloric feeding regimens can achieve adequate nitrogen balance with more favourable outcomes The prevalence of morbid obesity is increasing in the UK. Critical Care Medicine ; 32 : S—

Elaine Bromiley Aanesthetising April Elaine Bromiley died after there was difficulty in managing her airway after she was anaesthetised for routine nasal surgery. The patient is usually sedated rather than anaesthetised and a tube is inserted into the trachea via the mouth and larynx a tracheal tube. The capnograph, which detects exhaled carbon dioxide, is used almost universally in anaesthesia but only sporadically in ICUs. In addition, obese patients were more likely to die if they sustained airway complications in ICU. The report has several findings and recommendations; but those on obesity and the monitoring of breathing are among the most striking. Most patients who had complications that were reported to this project had identifiable risk factors such as obesity or head and neck cancer; these patients are at a much higher risk of airway complications than healthy patients undergoing anaesthesia and surgery.
