Evaluation of the clinical effect of vacuum sealing drainage technique in promoting the healing of the L incision in root bone fractures
Objective To compare the effects of vacuum sealing drainage with conventional drainage on the healing of L incisions in calcaneal fractures.Methods From June 2019 to June 2023,71 patients with calcaneal fracture were randomly divided into vacuum sealing drainage group(36 cases)and control group(35 cases)in this prospective study.Patients in the vacuum sealing drainage group underwent negative pressure occlusion drainage after surgery,maintaining negative pressure at-0.02-0.04 MPa and continuous attraction for 7-10 days.The control group was routinely placed with drainage tubes after surgery,and the drainage tubes were extracted 48 to 72 hours after surgery according to the drainage situation.The visual analogue scale(VAS)was used to assess the pain level of the two groups.The two groups were followed up for 3 months after surgery.The incision healing and drainage fluid were observed and recorded,and the Maryland scale was used to evaluate the recovery of foot function 3 months after surgery.Results The mean incision healing time[(16.361±2.045)d vs.(19.886±2.040)d]and average hospital stay[(20.832±5.002)d vs.(24.609±4.876)d]were shorter in vacuum sealing drainage group than those in the control group(P<0.05).Compared with the control group,the vacuum sealing drainage group had a higher grade of incision healing(P=0.000)and a lower incidence of incision complications[8.333%vs.37.143%](P=0.004).The volume of drainage fluid of the vacuum sealing drainage group was more than that of the control group[(183.438±34.293)ml vs.(74.076±27.418)ml](P=0.000).The positive rate of bacterial culture of drainage fluid was lower than that of the control group[2.778%vs.17.173%](P=0.009).One week after surgery,the VAS pain score in the negative pressure occlusion drainage group was significantly lower than that in the control group[(3.642±1.492)vs.(4.751±1.567)](P=0.003).Three months after surgery,Maryland's foot function score in the vacuum sealing drainage group was better than that of the control group[(84.972±5.690)vs.(76.857±7.554)](P<0.05).Conclusions The vacuum sealing drainage can reduce incision infection rates,incidence of adverse events as well as postoperative pain,and promote incision healing,shorten incision healing time and mean hospital stay,and ultimately promote the recovery of foot function after calcaneus fracture surgery.
