RESUMEN
Objective:To investigate the effects of ultrasound-guided bilateral erector spinal plane nerve block on postoperative pain and sleep quality in children with pectus excavatum undergoing Nuss.Methods:From February 2020 to December 2021, 40 children with pectus excavatum undergoing Nuss from Hunan Children′s Hospital were prospectively selected and randomly divided into two groups: group E (group E) with erector spinal muscle plane block combined with general anesthesia and group G (group G) , with 20 patients in each group. After general anesthesia, ultrasound guided plane nerve block of bilateral erector spinal muscles was performed in group E, and general anesthesia with tracheal intubation was performed in group G. The Visual Analogue Scale (VAS) Score were recorded at 2, 6, 12, 24 and 48 hours after surgery; The addition of sufentanil, the time of extubation of post anesthesia recovery room (PACU) and the time of leaving the PACU in each group were recorded; The effective pressure times of analgesic pump and the number of people for remedial analgesia were recorded. Pittsburgh sleep quality index (PSQI) was used to score the sleep quality of children before and 2 days after surgery. The occurrence of hypoxemia and restlessness after extubation, nausea and vomiting, pneumothorax, local anesthetic poisoning and other complications were recorded.Results:The VAS score of group E at 2, 6, 12 and 24 hours after operation was lower than that of group G (all P<0.05). There was no significant difference in VAS score 48 hours after operation between the two groups ( P>0.05). The time of decannulation and recovery of PACU in group E was shorter than that in group G (all P<0.05). Compared with group G, there were fewer cases of sufentanil added in group E during operation, and the number of analgesia pump pressing times and cases of postoperative remedial analgesia in group E were less than those in group G (all P<0.05). The PSQI score of sleep quality index 2 days after operation in group E was better than that in group G ( P<0.05). The incidence of hypoxemia, restlessness, nausea and vomiting in group E was lower than that in group G (all P<0.05). Conclusions:Ultrasound-guided bilateral erector spinal nerve block can effectively reduce postoperative pain and complications of NUSS in children with pectus excavatum, and can also reduce the amount of sufentanil used during the operation, improve the sleep quality after the operation, which is conducive to the recovery of children, and is worthy of promotion.
