obesity related hypoventilation

screening for ohs would require additional preoperative evaluation of morbidly obese patients with severe osa and suspicion of hypoventilation or resting hypoxemia. as the prevalence of obesity and morbid obesity increases worldwide, anesthesiologists are more likely to encounter patients with ohs for obesity- and nonobesity-related surgery. in patients with ph, etomidate is preferred for induction over propofol because of minimal effect on myocardial contractility and systemic vascular resistance.26 nitrous oxide can also worsen right ventricular ischemia by increasing pulmonary resistance and causing an obligatory decrease in the fraction of inspired oxygen (fio2).27 during local or regional anesthesia techniques, minimal sedation should be given to avoid airway obstruction, hypoventilation, and hypercapnia.




propofol, for example, is highly lipophilic and its pharmacokinetics are cardiac output dependent; thus, a high volume of distribution in obese patients should be dosed based on tbw.30 hydrophilic compounds like neuromuscular blockers should be dosed based on lbw, with the exception of succinylcholine. patients with ohs are at higher risk for perioperative complications and anesthesiologists should have a high index of suspicion in morbidly obese patients who have signs or symptoms of ohs. contribution: this author helped with drafting the assigned sections of the manuscript; critical revisions, assuring accuracy and integrity and final approval.
