Complications of propofol deep sedation for colonoscopy in marked obesity patients

What is it about?

The aim of this study was to evaluate and compare the complication rate of propofol deep sedation (PDS) for colonoscopy in marked obesity (BMI > 30) and non-obesity (BMI < 25) patients in a teaching hospital in Thailand.

Why is it important?

After matching age, gender, ASA physical status and indications of procedure, there were 100 colonoscopic procedures in group A (BMI< 25) and 33 colonoscopic procedures in group B (BMI > 30). All sedations were given by residents or anesthetic nurses directly supervised by staff anesthesiologist in the endoscopy room. There were no significant differences in patients' characteristics, sedation time, indication, overall complication rate, anesthetic personnel and mortality rate between the two groups. However, upper airway obstruction in group B was relatively higher than in group A. All complications were easily treated, with no adverse sequelae.

PDS for colonoscopic procedure in marked obesity patients by trained anesthetic personnel with appropriate monitoring was safe and effective, The complication rate of this technique in marked obesity (BMI > 30) patients was not different or worse than in non-obesity (BMI < 25) patients. Serious adverse events were rare in our population.
