- Brief Summary
This study compares general anesthesia and spinal anesthesia for vNOTE tubal sterilization. A direct comparison of these methods has not been done before for this surgical approach. Investigators will aim to compare the two methods to determine the differences in perioperative complications, postoperative pain, postoperative nausea and vomiting, and the time to get the patient ready for discharge from the recovery room.
- Detailed Description
Anesthesia is a controlled, temporary loss of sensation or awareness used to perform surgical procedures. Spinal anesthesia is commonly used in obstetrics and gynecology for vaginal procedures as well as cesarean sections. The use of spinal anesthesia for laparoscopic surgery is an adequate and safe alternative to general anesthesia which remains the gold standard. Vaginal Natural Orifice Endoscopic Surgery (vNOTES) is a minimally invasive laparoscopic approach used for tubal sterilization that is currently performed under general anesthesia. This study is proposing that spinal anesthesia is an adequate and safe alternative to general anesthesia for vNOTES tubal sterilization. If participants join the study, all other routine care will continue but the researchers will randomly assign participants, like flipping a coin, to one of two groups. Both types of anesthesia are commonly used but the researchers are doing this study because it is not known if spinal anesthesia is a better alternative than general anesthesia which is typically used. The goal is to find out what might be best for future patients. If it turns out the two types of anesthesia are about the same, then surgeons would know that choosing the type with fewer side effects still gives satisfactory results and allows for this surgery to be performed safely. The risks involved in participating in this study are the same as all other anesthetic and surgical procedures which have significant physical risks. If participants choose to enroll, there will be a 50/50 chance of being assigned to either the standard of care group which will receive general anesthesia or the experimental group which will receive spinal anesthesia. Benefits cannot be guaranteed but, It is possible participants could be assigned to a type of anesthesia that has fewer side effects.

- Arm && Interventions
Group Intervention Description General Anesthesia General Anesthesia This arm will receive general anesthesia for vNOTES surgery. Spinal Anesthesia Spinal Anesthesia This arm will receive spinal anesthesia for vNOTES surgery.
- Primary Outcome Measures
Name Time Method Incidence of perioperative complications performing VNOTES tubal sterilization with Spinal Anesthesia up to 7 days after surgery This study seeks to explore the feasibility of performing vaginal natural orifice transluminal endoscopic surgery (VNOTES) tubal sterilization under small-dose spinal anesthesia compared to the gold standard, general anesthesia, in healthy patients and to analyze postoperative complications.
- Secondary Outcome Measures
Name Time Method Rate of post-operative pain between patients immediately after the surgery To determine the differences in postoperative pain between patients in each anesthesia group based on a pain scale assessed post-operatively.
Occurrence of postoperative nausea/vomiting immediately after the surgery To determine the differences in the occurrence of postoperative nausea/vomiting (PONV) in a yes or no survey question.
Compare time until PACU discharge-to-home readiness between patients immediately after the surgery To determine the differences in time until post-anesthesia care unit (PACU) discharge-to-home readiness between patients postoperatively.
