Let's just call it 'evidence-based practice'.

OBESITY among the population in general and our patients in particular has been a rapidly expanding problem (no pun intended ...). For anesthesiologists, along with the weight gain come a host of related concerns: difficulty in airway management, significant comorbidities, and so on. In the same manner as the obstetric population's body mass index has been increasing, so, too, the use of spinal {i.e., subarachnoid) block for cesarean delivery has been increasing. Spinal anesthesia in the obese or morbidly obese parturient raises the additional question: Should the dose of local anesthetic be increased, decreased, or the same compared with the nonobese parturient? Although a definitive answer has remained elusive, the idea that spinal anesthetic doses for cesarean section in the morbidly obese need to be reduced has gained popularity.
