Significance of bispectral index monitoring during the patients after general anesthesia while leaving the post-anesthetic intensive care unit / 中国医师进修杂志

Objective To discuss the significance ofbispectral index (BIS) monitoring during the patients after general anesthesia while leaving the post-anesthetic intensive care unit (PAICU). Methods Seventy-five cases after general anesthesia were selected. When they were sent out of the PAICU, recorded their BIS. Results Twenty-one cases with BIS 90 - 100,48 cases with BIS 80 - 89 in slight calm and hypnosis,5 cases with BIS 70 - 79, and 1 case with BIS 50 - 60. Conclusions Without BIS monitoring,when sent out of the PAICU,most patients after general anesthesia are gently sedated and without too much risk. But still some patients are deeply sedated. BIS monitoring provides a nice reference for the patients while leaving the PAICU.

Intranasal low dosage sufentanil used in operation under local anesthesia / 中国医师进修杂志

Objective To observe effects of intranasal sufentanil on analgesia.Methods Eighty-two patients,who scheduled for selective thyroidectomy were randomly divided into the observed group and the control group with 41 cases in each group.In the observed group,patients received intranasal sufentanil 20 μg before the incision about 10 minutes,then administered local infiltration with 0.5% lidocaine.In the control group,patients received water for injection which was placebo instead sufentanil.By double blind method observed verbal mting scale(VRS)score.The values of NBP,HR,SpO2 and respiration rate(RR)were recorded before intranasal drugs and 5,10,20,40,60 min after intranasal drugs.The amount of local anesthetic,the size of thyroid gland,the time of operation and the satisfaction were compared between the two groups.Nausea vomiting and pruritus were also observed in order to assess the safety of intranasal sufentanil.Results All patients completed the operation successfully.The RR in the observed group decreased to(13.1±0.5),(13.8±0.6),(13.8±0.8)times/min after intranasal sufentanil 10,20,40 min,and had significant difference with those before intranasal drugs(P＜0.05),anastated after 60 min.VRS score of the observed group was(2.0±0.4)scales,less than the control group,and had significant difference when the surgeon was dissecting thyroid gland(P＜0.05).The amount of local anesthetic in the observed group was(42.5±6.9)ml,less than the control group(63.7±4.3)ml(P＜0.05).The satisfaction had significant difference between the two groups(P＜0.05).Conclusion Intranasal sufentanil for analgesia is a safe and useful technology.
