Change in Hemodynamics with Saddle versus Spinal Block in Patients Undergoing Elective Transurethral Resection of Prostate for Benign Prostate Hyperplasia

Abstract

Objective: To compare the mean change in hemodynamics with saddle block versus spinal block in patients undergoing
elective transurethral resection of prostate surgery for benign prostate hyperplasia.

Study Design: Quasi-experimental study.

Place and Duration of Study: Department of Anesthesia, Combined Military Hospital, Lahore Pakistan, from Oct 2019 to Apr 2020.

Methodology: A total of 80 patients were divided into two groups. Group-A (n=40) was dealt with spinal anesthesia and
Group-B (n=40) with saddle anesthesia. MAP and HR were measured at 0 and 5 minutes after anesthesia and change was
noted. Hyperbaric bupivacaine 0.75% was administered at level of L3 and L4 spinal levels. Midline approach was used under
aseptic conditions.

Results: The mean age of patients in spinal block Group-A was 56.40±12.01 years and in saddle block Group-B was
62.35±10.96 years. The mean change in MAP of spinal Group-A was 30.45±14.32mmHg and in saddle Group-B was
12.23±7.00mmHg. The mean HR in spinal Group-A was 66.35±4.91/min and in saddle Group-B was 74.88±5.17/min (p<0.05).

Conclusion: There was significantly more change of hemodynamics with spinal block than to saddle block undergoing elective Trans-urethral resection of prostate.
