Abstract:
Objective To investigate the clinical effect of normal pressure drainage immediately after posterior cervical expansive open-door laminoplasty(EOL).Methods A retrospective analysis was performed on 94 cases of posterior cervical EOL in our hospital from January 2023 to June 2023.The patients were divided into normal pressure drainage group(n=43)and negative pressure drainage group(n=51)according to the order of admission time.The time range of cases in the normal pressure group was from January to March 2023,while in the negative pressure group was from April to June 2023.The 24 h postoperative drainage volume,total postoperative drainage volume,drainage tube indwelling time,postoperative fever,incision infection,neck wound hematoma,Japanese Orthopaedics Association(JOA)score improvement rate before and after surgery,length of hospital stay,hospital cost and postoperative hemoglobin decline were compared between the two groups.Results The 24 h postoperative drainage volume of the normal pressure drainage group was significantly lower than that of the negative pressure drainage group[45(15-150)ml vs.170(70-400)ml,Z=-7.934,P=0.000].The total drainage volume in the normal pressure drainage group was significantly lower than that in the negative pressure drainage group[45(15-285)ml vs.315(165-730)ml,Z=-7.924,P=0.000].The drainage tube indwelling time was(27.1±13.9)h in the normal pressure drainage group and(82.2±20.6)h in the negative pressure drainage group,with statistically significant difference between the two groups(t=-14.933,P=0.000).The length of hospital stay was(3.5±1.1)d in the normal pressure drainage group and(5.6±0.8)din the negative pressure drainage group,with statistical significance between the two groups(t=-10.322,P=0.000).The postoperative hemoglobin decline was(13.9±3.1)g/L in the normal pressure drainage group and(16.5±7.2)g/L in the negative pressure drainage group,with statistically significant difference between the two groups(t=-2.165,P=0.033).The hospitalization cost was(3.00±0.30)ten thousand yuan in the normal pressure drainage group and(3.48±0.29)ten thousand yuan in the negative pressure drainage group,with statistically significant difference between the two groups(t=-7.924,P=0.000).There were no significant differences in intraoperative blood loss,postoperative fever and incision infection between the two groups(P＞0.05).There was no significant difference in the improvement rate of JOA score between the two groups during 3 months of follow-ups(t=0.861,P=0.391).Conclusion After posterior cervical EOL,normal pressure drainage reduces the postoperative drainage flow,indwelling time of drainage tube,hospital stay,and hospitalization cost,and does not increase postoperative hematoma,fever and wound infection and other complications,the clinical effect being significant.
