Summary
The letter discusses a study on ultrasonic control of puncture level for a neuraxial block in obstetric anesthesia. The author expresses concern about the arbitrary BMI cutoff of >30 used in the study and suggests that a BMI >25 should be considered overweight.
The letter emphasizes the need for local guidelines in the management of obese pregnant women, considering the increasing prevalence of obesity. The authors of the original study respond by explaining their rationale for choosing a BMI >30 as the cutoff and agree on the growing role of ultrasound in anesthesia practice, particularly for spinal procedures.
They highlight the benefits of ultrasound in demonstrating the limitations of traditional anatomical landmarks in the obstetric population.
