Objective To explore the diagnostic efficacy and safety of deep sedation anesthesia downlink peritoneal endoscopy.Methods in our 231 cases of peritoneal endoscopy patients as the research object,according to its will into deep sedation anesthesia group (group A,n=161)and non anesthesia group (group B,n=70)of two groups.Changes of blood pressure,heart rate and blood oxygen saturation and other indexes before and after comparison of two groups of patients endoscopy,record the related complications.Results before the examination,no significant difference be-tween the two groups of patients in blood pressure,heart rate and oxygen saturation contrast (P>0.05);inserted mirror,the above parameters in B group oxygen saturation with check before no variation,the rest were obviously in-spection before lifting,and no obvious change in A group with check before comparison with statistical significance difference comparison between the two groups (P<0.05);back mirror,two groups of patients were checked before each index had no significant difference (P>0.05);the endoscopy,A group of nausea and vomiting and pharyngeal discomfort in all 1 cases,the incidence was 0.6%,10 cases of restlessness (6.2%),30 cases of with the B group (42.9%),21 cases (13%)and 24 cases (34.3%)contrast differences are significant (P<0.05).Conclusion deep sedation should be for patients with peritoneal endoscopy anesthesia scheme,clinical effect is remarkable,worthy of popularization.

Objective To explore the lowest and most effective dose of dezocine in preventing postoperative pain after painless artificial abortion.Methods A total of 180 ASA Ⅰ ～ Ⅱ patients who accepted painless artificial abortion were randomly divided into 6 groups (n =30 patients per group).Group 1 (control) was given the placebo (0.9％ NS; 2 ml) by vein while other groups were given dezocine by vein with 0.01 mg/kg (group 2),0.02 mg/kg (group 3),0.03 mg/kg (group 4),0.04 mg/kg (group 5),and 0.05 mg/kg (group 6),respectively.The dosage of propofol,BP,HR,SpO2 during the operation,operation time,consciousness recovery time,analgesic effect (VAS score),leaving time,defecation feeling,and untoward reaction of each group were recorded and compared.Results The dosage of propofol in the 5 dezocine groups were significantly lower than that in the control group,respectively (t =2.38,4.72,6.03,4.57,3.96,P ＜ 0.05),while the difference in the operation time,consciousness recovery time and leaving time between the 5 dezocine groups and the control group had not statistical significance (P ＞0.05).The effect of postoperative analgesia and defecation feeling were apparently improved in the group 3,4,5 and 6,compared to the control group(group 3:x2 =3.36,6.94,P ＜ 0.05;group 4:x2 =7.17,15.01,P ＜ 0.05 ; group 5:x2 =15.5,24.3,P ＜ 0.01 ; group 6:x2 =13.01,20.24,P ＜ 0.01).Conclusions The lowest and most effective dose of dezocine was 0.05 mg/kg in preventing postoperative pain after painless artificial abortion.

Objective To select a proper posture for newborn from partus caesareus in order to prevent suffocation.Methods 120 cases of newborn from partus caesareus were selected.the respiratory tracts of the newborn were cleaned first by the operator.They were then laid on the warm platform in a posture of lying on side with head turning up a little.and sucked from their mouths and pharyngeal cavitieswhen circumstances required.The liquid quality was recorded.The distances between brow and occipital,back and occipital,head and shouders and the breast circumference were measured.From these datum the angles between back-occipital and the shoulders were calculated out.AIl these newborn were evaluated by APGAR 1 and 5 minutes after delivery by Partns caesareus respectively.Results Brow occipital distance(12.5±0.7),breast circumference(9.6±0.5),back occipital distance(4.2±0.5),head shouder distance(2.7±0.6);brow-occipital distancebreast circumference(P 0.05).85%of the new born need suction from mouth-cavities and pharyngeal space.9 cases were seen shedding ammiotic fluid from the corners of their mouths.There was no oxygen difficient case.no wrong drawing in.APGAR score after 1 and 5 minutes were more than 8.On leaving the operation room,their score were more than 9.3cases with scores from 6~7 had got scores more than 9 after being sucked from mouth cavities and pharyngeal space combined with mask oxygen therapy.None of them,on leaving the operation room needed trache-intubation.Conclusion Lying on side with head turning up a little is a proper posture to prevent newborn baby′s suffocation.

Objective To investigate the analgesic effect in childtbearing of ropivacaine of different density combined with sufentanil,and to observe the lowest effective denity of ropivacaine.Methods 90 cases of pregnant women desiring to prevent labor pain were selected.ASA.Ⅰ～Ⅱ grades,Head presentation,single-fetus,full-term gestation.They were divided into three groups randomly.A.(n=30) 0.1% ropivacaine +sufentanil 0.4μg/ml;B.(n=30) 0.074% ropivacaine +0.4μg/ml sufentanil.C.(contrast)(n=30) 0.1% ropivacaine +sufentanil 0.4μg/ml.Child-bearing anatgesia was carried out in the first active couse of labor.The pregnant woment's.HR、BP、RR、SpO2 were recorded.The analgesic effect was estimated by V.A.S. from 0～10.O.painless.10.excruciation pain.3 excellent effect,3～4 good effect,5 bad effect,5 failure.Estimation of motor nerves block was done by using improved Bromage method.The new-born was estimated by Apagar method.Results These three groups got satisfactory analgesic results.No difference was observed between these three groups(P0.01).Conclusion Ropivacaine combined with snfentanil can be used safely and satisfactorily to prevent pain in child-bearing.

Objective To investigate the effect of dexamethasone in the the prevention of untoward responses such as vomit,nausea and itch,caused by using patient-self controlled epidural analgesia after cesarean section.Methods Post-operative gynecological patients and cesarean women operated under epidural block were selected.The first group(experiment group) cesarean section 50 cases.The second group(contrast) gynecological operation 50 cases.P.C.E.A.(patient self-controlled epidural analgfesia) was carried out in both groups.The first group was treated with dexamethasone 10 mg I.V.The second group was treated with granisetron 4mg I.V.the analgesic effect,nausea,vomit,skin-itch and the time for recovery of digestive function were closely observed and recorded.Results The analgesic effect is excellent,there is no significant difference between,these two groups(P0.05).Of untoward responses such as nausea,voimit,no obvious difference is observed between these two groups(P0.05).The skin-itching rate is lower in group Ⅰand the time for digestive function recovery is shorter in group Ⅰ too.Conclusion Desamethasone can be effectively used to prevent these untoward responses such as nausea,vomit and skin-itching from using patient self-controlled epidural analgesia by women after cesarean section.
