Thoracic Spinal Anesthesia Achieves 97 Percent Success in Laparoscopic Hysterectomy, Suggests Study
A recent retrospective study published in the Indian Journal of Anaesthesia shows that thoracic segmental spinal anesthesia achieves a remarkable 97% success rate for total laparoscopic hysterectomy. By using single-injection isobaric bupivacaine and fentanyl, this regional technique delivers exceptional hemodynamic stability and rapid recovery as a compelling alternative to general anesthesia.
While total laparoscopic hysterectomy (TLH) is routinely conducted under general anesthesia (GA) to tolerate pneumoperitoneum and steep Trendelenburg positioning, systemic risks and post-laparoscopic shoulder pain under conventional regional techniques created a distinct clinical gap that prompted Dr. Richa Chandra and colleagues from Rohilkhand Medical College and Hospital to evaluate the feasibility, efficacy, and safety of single-injection thoracic segmental spinal anesthesia (TSSA).
Therefore, following STROBE guidelines, the single-center retrospective study evaluated 66 women aged 40–70 undergoing elective total laparoscopic hysterectomy under T11–T12 thoracic segmental spinal anesthesia between April 2023 and October 2025. After excluding 12 incomplete cases, researchers assessed block feasibility, hemodynamic stability, complications, and recovery times across a primary cohort of 50 standard-duration procedures.
Key Clinical Findings of the Study Includes:
- High Procedure Feasibility: The investigators documented a 97.0% success rate (64/66 patients) for completing TLH under regional block alone, with only 3.0% (2/66) requiring conversion to general anesthesia.
- Rapid Onset with Extensive Sensory Block: Authors noted a swift mean sensory block onset of 4.8 ± 1.1 minutes, consistently providing T3/T4–S3/S4 dermatomal anesthesia without significant lower limb motor impairment.
- Superior Hemodynamic Control: The study observed exceptional cardiovascular stability, with intraoperative hypotension occurring in only 10.6% (7/66) of cases and bradycardia in 6.1% (4/66), both responding promptly to single vasopressor or anticholinergic boluses.
- Minimal Shoulder Discomfort: Researchers recorded a low 6.0% (3/50) incidence of intraoperative shoulder pain, with zero occurrences of high spinal block, respiratory compromise, or neurological deficits.
- Accelerated Patient Mobilization: The team reported rapid postoperative recovery, characterized by a mean time to ambulation of 4.2 ± 1.5 hours and an average hospital stay of 1.8 ± 0.6 days.
The results suggest that thoracic segmental spinal anesthesia (TSSA) with isobaric bupivacaine and fentanyl provides safe, reliable sensory coverage from T3/T4 to S3/S4 while maintaining excellent hemodynamic control and low complication rates for standard-duration laparoscopic hysterectomies.
Thus, the study concludes that the regional approach provides clinicians with a practical, opioid-sparing anesthetic option that optimizes surgical visualization through reduced bowel distension while avoiding systemic intubation risks in gynecological laparoscopic cases.
Although limited by its retrospective, single-center design and modest sample size, these encouraging observations highlight the need for prospective randomized controlled trials to establish standardized clinical protocols.
