Significance of ultrasound-guided selective pudendal nerve block in patients undergoing vestibular gland resection and its effect on postoperative complications / 中国基层医药

ABSTRACT

Objective:To investigate the application value of ultrasound-guided selective pudendal nerve block during vestibular gland resection.Methods:Ninety patients who underwent vestibular gland resection in Lishui Maternal and Child Health Hospital from January 2017 to January 2020 were included in this study. These patients were divided into a control group and an observation group ( n = 45/group) according to the order of admission. Patients in the control group underwent blind nerve block and those in the observation group underwent ultrasound-guided selective pudendal nerve block. Hemodynamics before and after anesthesia, anesthetic effects, pain severity, and the incidence of complications were compared between the control and observation groups. Results:There were no significant differences in hemodynamics and pain severity between the control and observation groups (both P > 0.05). Systolic blood pressure [(124.37 ± 8.12) mmHg], diastolic blood pressure [(91.68 ± 5.44) mmHg] and heart rate [(74.62 ± 3.56) beats/min] were significantly lower than those in the control group [(128.62 ± 9.27) mmHg, (95.24 ± 6.17) mmHg, (76.12 ± 3.32) beats/min, t = 2.248, 2.903, 2.067, all P < 0.05]. In the observation group, pain scores at 2 and 24 hours after surgery were (3.06 ± 0.25) points and (4.21 ± 0.52) points, respectively, which were significantly lower than those in the control group [(3.28 ± 0.24) points and (4.54 ± 0.48) points, t = 2.618, 3.128, both P < 0.05). Anesthetic effect in the observation group was superior to that in the control group, and incidence of complications in the observation group was significantly lower than that in the control group ( χ2 = 12.869, 4.285, 4.864, 3.920, all P < 0.05). Conclusion:Ultrasound-guided selective pudendal nerve block in vestibular gland resection exhibits better anesthetic effect, has no obvious effect on hemodynamics, and has good analgesic effect with low incidence of complications. Therefore, it deserves clinical popularization.
