The Study On Effect Of2%Lidocaine Reducing Surgical Patients’ Pain Of IV Catheterization

Objective: The aim of this study was to compare the pain levels from the patients who willundergo gynecological laparoscopic surgery with or without application of2%lidocaine via jetinjector before intravenous catheter(IV catheter).And through the form of questionnaire, we wantto survey the condition that analgesia needs with (IV catheter) of patients and state of cogtition ofnurses, provides a method of security, economic, applicable in patients who need that, and makeefforts to achieve the humanistic nursing, increase the satisfaction of patients, ultimately improvethe quality of high quality nursing service.Methods: The study was a prospective, randomized, single-blind, placebo-controlled clinicaltrial.We had selected212gynecological laparoscopic surgery patients who need to use IVcatheter.212patients were randomized to two gtoups.122cases are in the observation group thatwe spray adequate amount2%lidocaine(completely into skin, about0.4ml)surround the puncturepoint which in the left vein from the wrist proximal part1-2cm within8*10cm range;next, spraythe same coverage with75%alcohol and according to the conventional preparation forintravenous transfusion(2minutes), then decontaminate the puncture point as thecenter(8*10cm)with0.5%iodophors disinfectant and fasten it after successful puncture.Whereasthe remaining90cases are in the control group receive an quual volume of saline, the rest is as thesame as the observation group.The patients were scored by VAS and recorded after the end of stu-dy, and a unified WHO grading of pain is adopted for judging the patient’s pain intensity.Next, tounderstand these212cases’ demand of IV catheter analgesia and the understanding of nursesabout it in this hospital by questionnaire.Apply the SPSS17.0statistical software package for dataanalysis, the VAS score and WHO pain intensity in two groups were compared using twoindependent sample t tests, P<0.05was considered statistically significant.using the percentage todescribe the patients’ demand of IV catheter analgesia and the understanding of nurses about it.Results: The VAS scores in pain of observation group was significantly lower than the controlgroup’s.The difference has the statistically significant(P<0.05).the pain assessment of the patientsin the observation group was markedly relieved (P <0.01) by using WHO pain grading. The studyfigures show that97.17%of cases had never thought to relieve the pain caused by venous IVcatheter though the way of narcotic drugs,100%of them never made any demand on paramedicsto use narcotic drugs to reduce pain caused by venous IV catheter.96%of paramedics had everthough to take any measures to relieve that pain on patients, only4%of them thoughtabout it, butnever implemented.Conclusion:2%lidocaine permeation provides pain relief for insertion of IV catheter isevidently. Cognition rate and level of attention about IV catheter analgesia both in patients andnursing staff itself would be very low.
