The Anesthesia Obesity difficult intubation devices. The consequences of failure to intubate may inyubation be serious if oxygenation can be maintained by facemask or with LMA ventilation. However emergency intubation in ICU is contemplated when there's a cardiac arrest, sudden deterioration of GCS requiring airway protection or sudden cardiovascular compromise massive bleed, left ventricular failure leading to pulmonary oedema. Oral laryngoscopy with a MAC 3 blade was attempted which revealed a grade 4 view no identifiable laryngeal anatomy. This could be explained by the large use of video laryngoscopes in our four OT centres in the case of difficult intubation. Suboptimal positioning would result in a higher incidence of grade 3 and 4 Cormack-Lehane laryngoscopy views, making direct laryngoscopy and hence tracheal intubation more challenging.
The consequences of failure to intubate may not be serious if oxygenation can be maintained by facemask or with LMA ventilation. Forgot Username? Troop is the inventor of a commercially available pre-formed positioning aid mentioned in this article. Preoperative assessment of the airways in the obese should include examination of specific predictors of difficult mask ventilation other than those for difficult intubation.

For the DL group metallic reusable blades sizes 3 and 4 were used for direct laryngoscopy. In addition, although most anaesthesiologists recommend the sniffing position and consider it to be essential for improving tracheal intubation [ 9 ], the superiority of this position has been questioned during the last decade [ 10 ]. We were surprised of the low rate of use of difficult intubation devices in ICU in this high risk context. Brock-Utne, M.

Issue Section:. Jay B. However, the definitions used for the recorded variables, that is, difficult difficklt, risk factors for difficult intubation, or severe life-threatening complications, were the same in both databases. Intubation Strategies for Awake Intubation Caution should be always taken when administering sedative drugs since airway obstruction may occur even with minimal sedation, especially in patients with OSA.
This is particularly true for the small subset of patients with MO who have features associated with both difficult mask ventilation and difficult intubation: massive central obesity, severe OSA, high Mallampati score, and short, wide neck. Category : Past ArticlesReview. The incidence of difficult intubation and related complications in obese patients admitted to intensive care unit ICU was twice as high as patients in the operating theatre OT. Declaration of interest. A higher incidence of difficult intubation has also been suggested in patients with morbid obesity, and so some clinicians choose awake intubation as their primary strategy for airway management. The well-known difficulties in airway management in obese patients are caused by obesity-related airways and respiratory changes.
Lack of a standard intubating position for patients with MO is a further cause of confusion. A modified version of the intubation difficulty scale mIDS was used to define easy versus difficult intubation, where a score of two or greater was defined as difficult intubation. Finally, Dr Nair mentioned that the Modified Mallampati Score performed in supine position is not reliable to predict difficulty of intubation. A complete reversal of neuromuscular block, measured by train-of-four monitoring, should be obtained before extubation, which requires a fully awake patient in the same position with airway equipment used for intubation.
Laryngeal Mask Airway (LMA)
Cook and colleagues 58 have reported that oesophageal intubation and aspiration are important and often precursors of fodboldklub obesity ditficult. For patients with MO requiring general anesthesia the airway should be secured with either a tracheal tube or laryngeal mask airway LMA. The main message of our study is not that patients are comparable between ICU than OT, because they clearly differ. Responses to five clinical questions determine the entry point into the DAA.
After obtaining local research ethics board approval forthis study and written informed consent was obtained from all patients. Our primary endpoint was the time required for successful intubation for each device.

On the whole the authors present valuable data relating to a patient obesity difficult intubation that form an increasingly common and often problematic proportion of ICU and OT patients - but does their comparison between the two very different environments really carry weight? May help minimize neck movement, ease of obtaining view of cords, may be used for rapid sequence, useful for teaching. Furthermore there is substance to the theory that intubation in the OT is more controlled than in the ICU , and this may also contribute to the overall reduction in complications and difficulties with intubation in obese theatre patients. A multivariate model was constructed using the intubations of obese patients in the OT where all data were available.

Head-elevated laryngoscopy position: improving laryngeal exposure during laryngoscopy by increasing head elevation. Laryngoscopy may be difficult in obese patients because of elevated chest diameter giving limited space for the laryngoscope positioning, limited neck mobility, and increased amount of fat tissue in the upper airway, including a larger tongue [ 56 ]. Therefore, the risk of difficult intubation was almost twofold higher in ICU than in OT in both obese and non obese populations. Search ADS. Future analyses should explore the association of BMI and difficult airway.

Declaration of interest. The difficult airway was defined by an ASA task force as the clinical situation in which a conventionally trained anesthesiologist experiences problems with face mask ventilation of the upper airway, tracheal intubation, or both. This might be an explanation for the severe complications in ICU. Therefore, the risk of difficult intubation was almost twofold higher in ICU than in OT in both obese and non obese populations. May help minimize neck movement, ease of obtaining view of cords, may be used for rapid sequence, useful for teaching.
Based on both our clinical experience at an active bariatric surgical center and on the few prospective studies that have addressed this issue, we question the validity of the general statement that obese patients are three times more difficult to intubate than their slimmer counterparts. Sign In. Continuing Education. Conclusion: Morbidly obese patients do not have a higher incidence of difficult intubation compared to non-morbidly obese patients. The well-known difficulties in airway management in obese patients are caused by obesity-related airways and respiratory changes.
Then, we excluded studies devices the initial review of deviecs title and after the abstract was reviewed due to they are not endotracheal intubation, letters, reviews, cross-sectional studies and case reports. However, subgroup analysis showed no trend of a higher association of obesity with a risk of DI compared with non-obesity in cohort studies and no association with an increased risk of difficult laryngoscopy in the sniffing position. Please see Caplan, et al. The use of videolaryngoscopes in morbidly obese patients not only improves glottic view but also makes intubation efforts easier and less traumatic [ 1415 ].
