BackgroundAnterior serratus plane block for analgesia in many procedures, but there have been no reports of analgesia undergoing laparoscopic cholecystectomy (LC). We investigated the effects of ultrasonic-guided low serratory anterior block on patients undergoing LC.MethodsOne hundred patients who undergo LC were selected and randomly divided into 2 groups: Patients in group C with routine general anesthesia and patients in group S treat low anterior serratus block combined with general anesthesia. The serratus anterior block was performed at the T8 to T9 point after anesthesia induction, before cutting leather (T0), stamp card placement (T1), 2 groups of patients' heart rate (HR), blood pressure were recorded, at the same time dosage of analgesic drugs and postoperative 0.5, 6, 12, 24 hours when resting visual analogue scale (VAS) scores were recorded in 2 groups of patients.ResultsThe T0 point, patients' HR, blood pressure had significant difference (P > .05), the T1 point, patients' HR, mean arterial pressure in group S lower than group C (P < .05), the amount of intra-operative propofol and remifentanil, patients in group S were less than in group C (P < .05), and resting VAS pain score at the 0.5, 6, 12 hours after operation patients in group S were lower than group C also (P < .05), resting VAS pain had no significant difference at postoperative 24 hours between 2 groups (P > .05).ConclusionLow serratus anterior plane block in LC can provide safe and effective analgesia for patients.Copyright © 2021 the Author(s).
