Morbid Obesity: what the trials found

Bupivacaine has been investigated as an intervention in patients with morbid obesity, showing significant results in pain management; specifically, trials reported mean Visual Analogue Scale (VAS) scores of 6.60, 6.15, 4.37, 3.11, 5.85, and 4.80 [1, 3]. Additionally, the use of a combination of morphine-0.1% and levobupivacaine resulted in mean changes from baseline in pain scores of 1.4, 1.6, 1.6, 0.8, 1.1, and 0.8 9.

Surgical interventions for weight management include the Swedish Adjustable Gastric Band (SAGB). One trial showed a -35.6% change in excess body weight at 5 years post-implant with a re-operation rate of 8.91% 7. Another study on SAGB reported a 41.1% excess weight loss, though it noted a 69.6% incidence of adverse events 10.

Pharmacological management using Dapagliflozin/Metformin demonstrated significant improvements in multiple metabolic markers, including reductions in weight (p<0.05), blood pressure (p<0.05), and waist circumference (p<0.05) 8. In procedural settings for morbidly obese patients, a dural puncture epidural (DPE) showed no significant difference in the number of participants requiring interventions like asymmetric blocks or emergency general anesthesia compared to standard care (p=0.766) 4. Other procedural findings include success at low insufflation pressure during certain procedures 6 and the use of Cefazolin 5 and Rocurinum 6.

Recent results — preliminary, needs further review

  • [“Opioid-Based Anesthesia (Remifentanil-Based Protocol)” is currently being evaluated in patients with morbid obesity 2.

For the clinician treating this condition

  • Bupivacaine and morphine/levobupivacaine combinations are established for pain management in this population [1, 3, 9].
  • Dapagliflozin/Metformin combination therapy significantly reduces weight, blood pressure, and waist circumference 8.
  • The Swedish Adjustable Gastric Band provides significant excess weight loss but is associated with a high rate of adverse events [7, 10].
