Effect of painless anesthesia instrument coordinated with nursing intervention during single tooth anesthesia for mandibular impacted tooth extraction

Abstract

Objective To investigate the effect of nursing intervention coordinated with painless anesthesia instrument during single tooth anesthesia for mandibular impacted tooth extraction.Methods 120 patients of mandibular impacted tooth extraction were randomly divided into two groups:the experimental group (60 cases) was given anesthetic by the WAND single tooth anesthesia while the control group (60 cases) was given conventional inferior alveolar nerve block anesthesia.Both groups received routine nursing,while the experimental group was given additional nursing intervention.Blood pressure (BP),pulse and heart rate (HR) of the patients were measured at various time intervals.The value of visual analogue scale (VAS) was also recorded and evaluated.Results The VAS score of the experimental group ( 1.582 ± 1.025 ) was significantly lower than that of the control group (4.935 ±7.513) and the difference was statistically significant.There was no significant difference of BP and HR of the experimental group before and after the anesthesia.Systolic pressure of the control group during the three stages of anesthesia and pest-operation was ( 116.18 ± 10.83),( 130.36 ± 10.15 ),( 131.66 ± 8.90),( 116.94 ± 10.29) mmHg,respectively.There was significant difference among the four intervals (F =126.735,P ＜ 0.01 ),DBP among the four intervals was statistically significant( P ＜0.01 ),HR was no difference( P ＞0.05).Significant differences were found of the changes of BP and HR at various timing of anesthesia between the two groups ( P ＜ 0.05 ).Conclusions The WAND single tooth anesthesia and effective nursing intervention produced a significantly lower pain score and safer anesthesia range than conventional inferior alveolar nerve block anesthesia.
