Research On The Preoperative Skin Preparation Methods Of Neurosurgery

Surgical site infection(SSI) is one of the main factors which lead tohospital infection, accounting for14.0%-16.0%in all patients infected inhospital[1].The rate of nerve surgical site infection is1-4%,accounting for14%of postoperative mortality.SSI is one of the most severecomplications after surgery, in addition, it can directly cause to increasein a sustained hospitalization,and associated with increase inexpense~[3].The skin preparation to prevent SSI as one of the mostimportant measures has always been playing an important role. TheUnited states centers for disease control and prevention has issued asurgical control guidelines in1994[4], which has clearly stated the generalprinciple and methods of the skin preparation before surgery, however,there is no specific guidance of skin preparation in some particularoperation parts (such as head). In recent years, scholars have carried outextensive exploration and research on the head skin preparation beforeneurosurgery operation, but no consensus was reached. Thus choosing thehead skin preparation method has important guiding significance inpreoperative care of Neurological Surgery.Objective: looking for the appropriate skin preparation method ofpatients after neurological surgery by comparing the clinical effectsbetween comparing the shearing of the skin preparation method and the traditional shaving is to provide evidence for preventing SSI.Methods:this study used types of experimental research method.According tothe inclusion criteria,100cases of patients after neurological surgery inChina-Japan Union hospital has been selected, among which60cases incomparison group,40cases in test group. Patients in test group has beengiven electronic machine to prepare skin and bacteriostatic agent called“JiaoNa” to clean; The comparison group uses the traditional hemostaticforceps clip blade method or one-time preserved skin knife to prepareskin according to routine operation for skin. At the same time record thenurse operation time, and using the scalp damage degree evaluation sheetand patient satisfaction questionnaire to assess patients.sampling andculture bacteria on the skin of the surgical site before half an hour insurgery site, in order to compare the two skin preparation of the surgicalsite in the bacterial detection rate of half an hour before surgery.Results:using the scalp damage degree evaluation sheet to assess patients,the damage degree of test group was significantly lower than thecomparison group, the difference was statistically significant(P<0.05);Recording the nurse operating time results showed nosignificant difference between the test group and the control group, thedifference was not statistically significant (P>0.05); Patient satisfaction survey results showed that the test group patients was significantly higherthan that in comparison group, the difference was statisticallysignificant(P<0.05); sampling and culture bacteria on the skin of thesurgical site before half an hour showed that the bacteria rate of test groupwas evidently lower than comparison group, the difference wasstatistically significant(P <0.05).Conclusion:Compared with traditional shaving skin preparation, shearingmethod can significantly reduce the degree of injury of the scalp, andimprove patients’ satisfaction, but no difference in the operating time.Electric shearing skin preparation method is a better scalp skinpreparation.
