Summary
Narcotic anesthesia during cholecystectomy impacts biliary tract resistance. Morphine sulfate increased resistance in normal ducts, unlike fentanyl citrate, which showed no significant difference compared to nonnarcotic anesthesia.
Area of Science:
- Anesthesiology
- Gastroenterology
- Surgical Physiology
Background:
- Biliary tract resistance is a critical factor during cholecystectomy.
- Anesthesia techniques may influence intraoperative physiological parameters.
- Understanding the impact of different anesthetics on the biliary system is crucial for patient safety.
Purpose of the Study:
- To investigate the effect of narcotic and nonnarcotic anesthesia on biliary tract resistance during cholecystectomy.
- To compare the influence of fentanyl citrate and morphine sulfate on biliary duct pressures.
Main Methods:
- Biliary tract resistance was measured in 142 patients undergoing cholecystectomy.
- Patients received either narcotic (fentanyl citrate or morphine sulfate) or nonnarcotic anesthesia.
- Intraoperative pressures in normal bile ducts were recorded and analyzed.
Main Results:
- Fentanyl citrate (narcotic) anesthesia did not alter biliary tract resistance in normal ducts compared to nonnarcotic anesthesia.
- Morphine sulfate administration resulted in elevated biliary tract resistance in 5 out of 7 patients with normal ducts.
- A significant difference in biliary tract resistance was observed with morphine sulfate compared to nonnarcotic anesthesia.
Conclusions:
- The choice of narcotic anesthetic agent can affect biliary tract resistance during cholecystectomy.
- Morphine sulfate may increase biliary tract resistance, potentially impacting surgical outcomes.
- Fentanyl citrate appears to be a safer option regarding biliary tract resistance during this procedure.
