Randomized Controlled Trial
Treatment with lavender aromatherapy in the post-anesthesia care unit reduces opioid requirements of morbidly obese patients undergoing laparoscopic adjustable gastric banding.
Parenteral administration of opioids and NSAIDs has been the mainstay for postoperative pain control in patients undergoing laparoscopic adjustable gastric banding (LAGB). Both classes of drugs, however, are associated with serious adverse effects. An addition of complimentary analgesic techniques may decrease requirement for traditional analgesics, thus reducing the incidence of side-effects. We designed the study to evaluate the effectiveness of Lavender aromatherapy in reducing opioid requirements after LAGB. ⋯ Our results suggest that lavender aromatherapy can be used to reduce the demand for opioids in the immediate postoperative period. Further studies are required to assess the effect of this therapy on clinically meaningful outcomes, such as the incidence of respiratory complications, delayed gastric emptying, length of hospital stay, or whether this therapy is applicable to other operations.
