Abstract Background: Intubation procedure in obese patients is a challenging issue both in the intensive care unit ICU and in the operating theatre OT. Ramped position: This position was achieved by elevation of the shoulders and the head till achieving alignment of the sternal notch and the external auditory meatus as shown in Fig.

In essence, how much of the risk from intubation on ICU relative to intubation in theatres was actually related to obesity. AH and TA: These authors helped in conception intubating obese patients the idea, study design, analysis of the data, and drafting the manuscript. This study highlights the fact that the ICU setting is an independent risk factor of severe complications, in comparison with the OT setting. It has been shown that preoperative CPAP decreases severe hypoxemia, pulmonary vasoconstriction, hospital length of stay and postoperative complications.

To provide intubating obese patients, the anaesthetist may insert a tube through the mouth or nose and down the trachea windpipe into the lungs. We were surprised of the low rate of use of difficult intubation devices in ICU in this high risk context. Obes Surg ;—5. 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.

In addition, difficult intubation devices were used more often in the case of difficult intubation in the OT than in ICU. Conversely, some studies after reached a different conclusion, indicating that a high body mass index BMI was not associated with DI [ 78 ].

Obese patients were slightly more difficult to intubate compared to lean patients based on IDS. In subgroup analysis, intubating obese patients was not associated with an increased risk of difficult laryngoscopy in the sniffing position compared with non-obesity. However, there was no association between obesity and risk of DI compared with non-obesity in cohort studies and elective tracheal intubation and no association between an increased risk of difficult laryngoscopy in the sniffing position. By this time, most critically ill patients are entering the low saturation zone.

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. Increased metabolism leads to increased cardiac output and more blood flow across the kidneys. The seated, ramped and reverse Trendelenburg position all decrease the abdominal interference with diaphragmatic excursion, which opens up functional residual capacity as well as lessens he amount of chest wall weight restricting chest wall compliance; this makes ventilation easier. This may take a second or two. The modified-ramped position would help to avoid the hazards of re-positioning of the patient which is common in obese females; and would consequently avoid unwarranted delay in the endotracheal intubation process.

Neck circumference 35 and neck circumference to thyromental distance 36 were not available in our OT database, even if defined as risk factors of difficult intubation in obese patients in previous studies. Modified-ramped position provided better intubating conditions, improved the laryngeal view, and eliminated the need for repositioning of obese female patients during insertion of the laryngoscope compared to ramped position. As clearly stated by Dr Nair, airway examination and documentation of findings should be part of ICU practice, in order to predict difficult intubation, using for example the MACOCHA score [3], and to decrease the complications related to unanticipated difficult intubation, with the help of an airway algorithm, inspired by what already exists in OT, but specifically dedicated to ICU setting.

Therefore, we suggested that manual mobilization of the head would be performed as a rescue maneuver in case of difficult visualization of the intubatign however, we found that, the laryngeal view was better in modified-ramped position and the planned rescue maneuver was not needed in any patient. What is the best way to determine oropharyngeal classification and mandibular space length to predict difficult laryngoscopy? None of our patients had significant hypoxemia nor airway trauma.

Insertion of the laryngoscope in the mouth cavity is usually difficult in obese females [ 9 ]. De Jong, Intubatjng.
