ABSTRACT
Objective To investigate optimum dose of anesthesia in pediatric axillary brachial plexus branch block under ultrasound-guided. Methods Forty-eight children from May 2012 to May 2013 in hand surgery of our hospital,whose age was from 6 to 12 years,were randomly divided into four groups, each group has 12 cases. The doses of Ropivacaine were different in different groups. Group A was 0. 25 mL/kg,group B was 0. 2 mL/kg,group C was 0. 15 mL/kg,group D was 0. 10 mL/kg. And Ketamine was added to the treatment ac-cording to the incidence of anesthesia intraoperative. Evaluating the effect of anesthesia according to the situation of nerve block,observing an-esthesia duration time,dosage of anesthesia and rates of complications. Results The blocking effect of group A,B and C in each nerve area was correspond after 30 min,and anesthesia efficiency was higher than group D,but additional rate was lower than group D,the differences were statistically significant (P<0. 05). The block time in group D was shorter than the other groups,and the dose of Ketamine was most, and the block onset,perfect time were longer than the other groups (P<0. 05). But the differences between group A,B,C were not signifi-cant. Two cases in group D converted to general anesthesia. Four groups did not occur complication related narcotic drug. Conclusion In pediatric brachial plexus block used Ropivacaine under ultrasound-guided would get complete branch block,the exact effect of anesthesia, smaller dosage of local anesthesia. When the dosage of Ropivacaine was 0. 15 mL/kg could achieve a better anesthesia effect.
ABSTRACT
Objective To design an adjustable frame for four limbs disinfection, and applied it to clinic, to prevent skin damage of eatagmatic limb due to heighten the limb for the preoperative disin-fection.Methods 180 patients who need to heighten limb for diaplasis were divided into the observation group and the control group averagely according to the sequence of operation time.Patients in the observa-tion group were heighten limbs by using the adjustable frame, while the control group were heighten limbs onto the fluid frame by traditional methods.Skin lesions, the contamination of the limb and the time for disinfection were observed.Results Skin lesions of the observation group and the control group were 2% and 20%, re-spectively,the difference was statistically significant.There was no case in the observation group was contami-nated and 16 cases were contaminated in the control group, the difference was statistically significant.The aver-age time for disinfection in the observation group was (17.6 ± 2.4)minutes, in the control group,(21.3 ± 3.2) minutes, the difference was also statistically significant.Conclusions Using the adjustable frame for limbs disinfection can reduce the skin damage, shorten the disinfection time and improve work efficiency.
