Abstract:

Objective

To compare the influence of quadratus lumborum block (QLB) and transversus abdominis plane block (TAP) on postoperative analgesia effect in patients undergoing laparoscopic inguinal hernia surgery.

Methods

128 patients who underwent elective laparoscopic inguinal hernia surgery from January to December 2022 were selected and divided into QLB group(general anesthesia combined with QLB; n=64) and TAP group (general anesthesia combined with TAP;n=64) according to the random number table method.The heart rate (HR), blood oxygen saturation (SpO2)and mean arterial pressure (MAP) at different time points, surgical time and nerve block duration were recorded in both groups, and the postoperative visual analogue scale (VAS) score was compared.The postoperative additional analgesic drugs were recorded, and the stress response [cortisol (Cor),norepinephrine (NE), aldosterone (ALD)] before and after surgery and occurrence of adverse reactions were compared between the two groups.

Results

There were no statistically significant differences in HR, SpO2 and MAP from the aspects of between-group, time-point and interaction effect (P>0.05).HR,SpO2 and MAP at T2-4 in TAP group were lower than those at T0 (P<0.05), and HR and MAP at T1-3 in QLB group were lower than those at T0, and SpO2 at T1-2 was lower than that at T0 (P<0.05).The duration of nerve block in QLB group was significantly longer than that in TAP group (P<0.05), but there was no significant difference in surgical time between the two groups (P>0.05).There was statistically significant difference in VAS from the aspects of between-group effect, time-point effect and interaction effect between the two groups (P<0.05).The VAS score in the two groups increased with time from 2 hours to 12 hours after surgery (P<0.05), and decreased with time from 12 hours to 48 hours after surgery (P<0.05).VAS scores in QLB group at 4, 8, 12, 24 and 48 hours after surgery were significantly lower than those in TAP group (P<0.05).The number of cases with additional analgesic drugs in QLB group was significantly less than that in TAP group at 24 and 48 hours after surgery (P<0.05).The levels of Cor, NE and ALD after surgery increased in both groups (P<0.05), but the levels in QLB group were significantly lower than those in TAP group (P<0.05).There was no significant difference in adverse reactions between the two groups(P>0.05).

Conclusion

Compared with TAP, QLB has better analgesia effect and longer nerve block time,and can reduce the stress response caused by pain stimulation, which is safe and worthy of application..
