Objective To determine how inter-semispinal plane block(ISPB)affects how well in-dividuals recover after having posterior cervical surgery.Methods Seventy-two patients chosen for elective posterior cervical surgery from January to April 2023,41 males and 31 females,aged 18-64,BMI 18-28 kg/m2,ASA physical status Ⅱ or Ⅲ,were divided into two groups using randomized block design:the ISPB group(group I)and the control group(group C),36 patients in each group.Before anesthesia induc-tion,all patients were positioned at the 5th cervical vertebra plane using ultrasound,and 0.25%ropivacaine 20 ml or the same volume of physiological saline were injected into the fascia plane between the bilateral semispinalis cervicis and semispinalis capitis muscles.Anesthetic induction began 15 minutes after injection.QoR-40 and Pittsburgh sleep quality index(PSQI)were recorded 1 day before surgery,1 day and 2 days after surgery,and pain numerical scores(NRS)were recorded 1,6,12,24,and 48 hours after surgery.The number of effective PCIA compressions,the total number of PCIA compressions,the number of relief analgesia,the dosage of sufentanil,remifentanil intraoperatively and postoperatively,and dosage of pentazo-cine postoperatively were recorded.The occurrence of postoperative nausea and vomiting(PONV),the time of first independent walking and oral feeding after surgery,and puncture related complications,such as he-matoma,infection,and local anesthetic poisoning were recorded.Results Compared with 1 day before sur-gery,the total QoR-40 scores and various dimensional scores in the two groups were significantly decreased,while PSQI were significantly increased 1 day and 2 days after surgery(P<0.05).Compared with group C,the total QoR-40 scores and various dimensional scores except self-care capacity were significantly in-creased,while PSQI were significantly decreased 1 day and 2 days after surgery(P<0.05),NRS were significantly decreased 1,6,12,and 24 hours after surgery(P<0.05),the number of effective PCIA compressions,the total number of PCIA compressions,the number of relief analgesia,the dosage of remifentanil intraoperatively,the dosage of pentazocine postoperatively and the occurrence of PONV were significantly decreased(P<0.05),the time of first independent walking and oral feeding after surgery were significantly shortened in group Ⅰ(P<0.05).There were no puncture related complications occurred in the two groups.Conclusion Bilateral ISPB can effectively improve the postoperative sleep of patients undergoing posterior cervical surgery,reduce postoperative pain and the incidence of PONV,and improve the postoperative recovery quality.
