PURPOSE: Postoperative pain and nausea/vomitting (PNV) are common in laparoscopic cholecystectomy patients. Sympatholytic agents might decrease requirements for intravenous or inhalation anesthetics and opioids. In this study we aimed to analyze effects of esmolol on intraoperative anesthetic-postoperative analgesic requirements, postoperative pain and PNV. METHODS: Sixty patients have been included. Propofol, remifentanil and vecuronium were used for induction. Study groups were as follows; I - Esmolol infusion was added to maintenance anesthetics (propofol and remifentanil), II - Only propofol and remifentanil was used during maintenance, III - Esmolol infusion was added to maintenance anesthetics (desflurane and remifentanil), IV - Only desflurane and remifentanil was used during maintenance. They have been followed up for 24 h for PNV and analgesic requirements. Visual analog scale (VAS) scores for pain was also been evaluated. RESULTS: VAS scores were significantly lowest in group I (p = 0.001-0.028). PNV incidence was significantly lowest in group I (p = 0.026). PNV incidence was also lower in group III compared to group IV (p = 0.032). Analgesic requirements were significantly lower in group I and was lower in group III compared to group IV (p = 0.005). Heart rates were significantly lower in esmolol groups (group I and III) compared to their controls (p = 0.001) however blood pressures were similar in all groups (p = 0.594). Comparison of esmolol groups with controls revealed that there is a significant decrease in anesthetic and opioid requirements (p = 0.024-0.03). CONCLUSION: Using esmolol during anesthetic maintenance significantly decreases anesthetic-analgesic requirements, postoperative pain and PNV.

Abstract The mechanism of the antidepressant effect of bupropion is not fully understood. Besides, using it in the treatment of depression, it is found to be effective in reducing withdrawal symptoms due to smoking cessation. A 28-year-old female patient with a history of depression was admitted to emergency department an hour after ingestion of bupropion, quetiapine, and levothyroxine in high doses to commit suicide. While accepting her into the Intensive Care Unit, she was awake, alert, disoriented and agitated. After 2 h, the patient had a generalized tonic-clonic seizure. The necessary treatment was given and 9 h later with hemodynamic improvement, the patients’ mental status improved. Bupropion may cause unusual behaviors such as delusions, paranoia, hallucinations, or confusion. The risk of seizure is strongly dose-dependent. We want to emphasize the importance of early gastric lavage and administration of activated charcoal.
