Effect of enhanced recovery after surgery concept in pediatric patients of abdomen surgery / 临床麻醉学杂志

ABSTRACT

Objective To observe the clinical effect of ultrasound-guided quadratus lumborum block combined with enhanced recovery after surgery (ERAS) for the laparoscopic appendectomy in children. Methods A total of 154 children undergoing laparoscopic appendectomy, 114 males and 40 females, aged 3-10 years, ASA physical status Ⅰ or Ⅱ, were divided into the ERAS group (group E) and control group (group C), n = 77 each group. Patients in group E received ultrasound-guided deep injection of 0.2％ ropivacaine 0.75 ml/kg into quadratus lumbar muscle. According to the guidelines for rapid rehabilitation fasting for 4 h and abstaining from drinking for 2 h, functional beverages were given 30 min before operation and parental escort during induction of anesthesia while given general anesthesia with laryngeal mask, that is, propofol 2-6 mg·kg-1·h-1 was continuously pumped with 2％-6％ sevoflurane. Patients in group C were given traditional anesthesia, strict fasting for 6 h and no drinking for 4 h, as while as induction with midazolam, propofol, atracurium and sufentanil and tracheal intubation. The VAS scores at 2, 3, 6 and 12 h post-operation were recorded. The awakening time, anal exhaust time, ambulation time, hospitalization days, the patient's satisfaction rates were recorded. The cases of nausea, vomiting, regurgitation and aspiration were recorded. Results The VAS scores at 2, 3, 6 and 12 h post-operation in group E were significantly lower than that in group C (P ＜ 0.05). All the postoperative rehabilitation indicators in group E were superior to group C, including the awakening time, anal exhaust time, ambulation time, hospitalization days and patient's satisfaction (P ＜ 0.05). Complication incidences in group E were significantly declined compared with group C (P ＜ 0.05). Conclusion For children undergoing laparoscopic appendectomy, ultrasound-guided quadratus lumborum block combined with the ERAS strategy could result in less postoperative complications, reduced postoperative pain, rapid rehabilitation, shortened hospitalization time and increased patients' satisfaction.
