Abstract:
Objective To explore the effect of lidocaine aerosol on alleviating the pain of intravenous puncture before the operation when the local skin spraying anesthesia was used the different time interval and the dose.Methods One hundred and eighty patients undergoing elective operation received the surface spraying anesthesia through the lidocaine aerosol in intravenous puncture site .The patients were divided into A group (4.5 mg) and B (9 mg) group according to the dose of lidocaine aerosol , and the puncture was carried out 3 min, 5 min, 7 min after the medication (A1, A2, A3, B1, B2, B3).The pain was evaluated by numeric pain intensity scale ( NPIS) , and the satisfaction was evaluated by the questionnaire of patients ’ satisfaction in two groups.Results The scores of NPIS in the A and B group were respectively (5.3 ±1.0), (4.9 ±1.1) 3 min after the medication, and the difference was not statistically significant (t=1.17, P>0.05);the scores were respectively (3.9 ±1.2), (2.9 ±1.6) after 5 min, and the difference was statistically significant (t=2.33, P<0.05);the scores were respectively (1.9 ±1.2), (0.9 ±0.7) after 7 min, and the difference was statistically significant (t=2.94, P<0.01).The differences were found in the scores of the NPIS in the A and B group at the different time including 3,5,7 min (F=46.13,56.10, respectively; P<0.01), the degree of pain was relieved in all patients with the extension of time .The rates of satisfaction in the A and B group were respectively 79%, 92%, and the difference was statistically significant (χ2 =6.47, P <0.05 ). Conclusions The effect of lidocaine aerosol on alleviating the pain of intravenous puncture before the operation is obvious.4.5 mg lidocaine aerosol is sprayed twice in surface anesthesia puncture site seven minutes before the injection, which can cause the good analgesic effect .The method of the medication should be reasonably and correctly mastered , which is beneficial to give full play to the analgesia effect and can increase the patients ’ satisfaction of nursing in the operation room .
