ABSTRACT
Objective To observe the effect of body temperature protection on enhanced recovery after surgery of patients undergoing laparotomy radical gastrectomy.Methods Sixty of patients ASA physical status Ⅰ or Ⅱ,aged 45-76 years,scheduled for elective radical gastrectomy were ran domly divided into 2 groups (n=30 each):heating blanket group and control group.In the heating blanket group,patients were warmed up during the whole perioperative period using the warmblanket until discharge from PACU;exposed skin as covered with clean surgical dressing;infusion,irrigation fluids and blood transfusions were warmed to 40℃;the bacteriological and viral filters were placed between the Y-piece of the breathing circuit and the tracheal tube.In the control group,patients were not given special heat preservation measures.For temperature measurements,an infrared tympanic ear thermometer was used.The core temperature of two groups were recorded at the pre-operative period (T1),before induction (T2),1 h after induction (T3),closing (T4),extubation （T5),discharging from PACU (T6).The dosage of anesthetic drug,volume of fluids infused,peritoneal fluid flushing volume,operation time,anesthesia time,ambient temperature,amount of bleeding,intrao perative blood transfusion,shivering,extubation time,incision infection and hospitalization time were recorded.Results There was no statistical difference in terms of temperature at T1 between the two groups.Compared with the T1,the core temperature of two groups of patients in T2-T6 were signifi cantly decreased (P ＜0.05).The perioperative core body temperature at T2-T6 was significantly higher in the heating blanket group than in the control group.The amount of bleeding and blood transfusion in perioperative period was significantly less that in the heating blanket group (P＜0.05).The incidence of shivering and surgical-wound infection were significantly lower in the heating blanket group (P＜0.05).The extubation time and hospitalization time were shorter in the heating blanket group (P＜0.05).Conclusion Combined body temperature protection measures can significantly reduce the incidence of inadvertent perioperative hypothermia (IPH) and improve postoperative outcomes for patients undergoing laparotomy radical gastrectomy.
ABSTRACT
Objective To observe the effect of ultrasound-guided abdomen nerve block combined with remifentanil infusion in cesarean section in patients with thrombocytopenia. Methods Sixty parturients recruited for the first cesarean delivery with thrombocytopenia (Plt<7.0 ×109/L),aged 20-32 years,in ASA physical status Ⅰ or Ⅱ,having no preterm birth and no fetal distress before surgery,were randomly divided into two groups:transversus abdominis plane block, ilioinguinal-iliohypogastric nerve block combined with remifentanil group (group T)and general anes-thesia group (group G).Both groups received patient-controlled intravenous analgesia (PCIA)after cesarean delivery;the delivery time from the cut to the fetus,Apgar score after delivery of the fetus, hemodynamics of the two groups of patients before surgery (T1 ),immediate cut (T2 )and fetal deliv-ery (T3 )and 48 h postoperative analgesic satisfaction were recorded and compared between the two groups.Results Compared with group G,the delivery time from the cut to the fetus was extended in group T (P < 0.05 ),but the fetus were removed within 6 minutes in the two groups.The Apgar score of 1 min after birth of newborns was significantly higher in group T than that in group G (P <0.05).Compared with group G,the blood pressure and the heart rate had increased at T3 in group T (P <0.05 ),but the parturients did not appear obvious symptoms.Compared with group G,the number of successfully delivered doses within 48 h were significantly lower in group T (P <0.05 ), TAP guided by sonography had excellent effect.Conclusion Ultrasound-guided abdomen nerve block combined with remifentanil infusion in cesarean section has little effect on neonatal,similar anesthesia effect to general anesthesia and obvious postoperative analgesia.
ABSTRACT
Objective To evaluate the effects of oxycodone combined with incision infiltration with ropivacaine on postoperative outcomes in the patients undergoing laparoscopic cholecystectomy.Methods Eighty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 33-64 yr,weighing 45-88 kg,scheduled for elective laparoscopic cholecystectomy under general anesthesia,were divided into 2 groups (n=40 each) using a random number table:patient-controlled intravenous analgesia group (group P) and oxycodone combined with incision infiltration group (group O).In group P,fentanyl 1-2 μg/kg was intravenously infused after cholecystectomy,and patient-controlled intravenous analgesia was performed with sufentanil at the end of surgery.In group O,oxycodone 0.05-0.10 mg/kg was intravenously injected after cholecystectomy,incision infiltration was performed with 0.5％ ropivacaine before suturing,and visual analog scale score was maintained ≤ 3.The emergence time,time to first flatus,time to liquid diet,first ambulation time,length of hospital stay after operation and adverse reactions were recorded.Results Compared with group P,the time to first flatus,time to liquid diet,first ambulation time and length of hospital stay after operation were significantly shortened,the incidence of urinary retention and nausea and vomiting was decreased (P＜0.05),and no significant change was found in the emergence time in group O (P＞0.05).Conclusion Combination of oxycodone and incision infiltration with ropivacaine can promote postoperative outcomes in the patients undergoing laparoscopic cholecystectomy.
ABSTRACT
Objective To observe the influence of combined spinal and epidural anesthesia( CSEA) of different po-sitions on the anesthesia effect, anesthesia operation and hemodynamic index during cesarean section of obese par-turients. Methods Eighty obese parturients[BMI≥30] undergoing cesarean section were randomly divided into two groups, that was group A and B, with 40 cases each. In group A, the parturients were required to undergo lat-eral decubitus position with 0.5% ropivacaine hydrochloride of 2. 4 ml. In group B, the parturients were required to undergo sitting position with the same ropivacaine hydrochloride as group A. The following data was recorded, which were the percentage of one-attempt's successful epidural needle placement, the anesthesia level,the anesthe-sia effect and the hemodynamic change. All the complications were also observed,such as the supine hypotension syndrome during operation,headache after spinal anesthesia and postoperative spinal nerve stimulation. ResultsThe difference of anesthetic effect between the two groups was insignificant in statistics while group B's rate of one-attempt successful puncture was higher than gruop A ( P <0.05 ) . The difference of hemodynamic index between them was significant in statistics ( P<0.05 ) with group B's rate of supine hypotension syndrome lower than group A. Conclusion Both body positions have the same anesthtic effect for obese parturients during cesarean section while the puncture operation of sitting positon is easier than lateral decubitus position and the hemodynamic change is also more stable.
ABSTRACT
Objective To investigate the effects of parecoxib pretreatment on the intrapulmonary shunt during one-lung ventilation in patients undergoing esophageal cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients of both sexes,aged 25-64 yr,weighing 45-70 kg,with body height 156-178 cm,undergoing elective esophageal surgery,were randomly divided into 2 groups (n =20 each):normal saline group (group NS) and parecoxib group (group P).Parecoxib 40 mg (in normal saline 10 ml) was injected intravenously 30 min before anesthesia in group P,while the equal volume of normal saline was given instead of parecoxib in group NS.Anesthesia was induced with iv injection of propofol,fentanyl and rocuronium.Bronchial blocker was inserted after tracheal intubation and the correct position was confirmed by bronchoscopy.Anesthesia was maintained with iv infusion of propofol and remifentanil and intermittent iv boluses of atracurium.HR,MAP,SpO2 and mean airway pressure (Pmean)were determined at 5 min of two-lung ventilation,at 40 min of one-lung ventilation,and at 30 min after re-expansion of the collapsed lung (T0-2).Blood samples were taken simultaneously from jugular vein and radial artery for blood gas analysis.Intrapulmonary shunt (Qs/Qt) was calculated.Results There were no significant differences in hemodynamic parameters and Pmean between the two groups (P ＞ 0.05).PaO2 was significantly lower,while Qs/Qt was significantly higher at T1,2 than at T0 in groups NS and P (P ＜ 0.05).PaO2 was significantly higher,while Qs/Qt was significantly lower at T2 than at T1 in groups NS and P (P ＜ 0.05).Qs/Qt was significantly lower at T1,2 and PaO2 was significantly higher at T2 in group P than in group NS (P ＜ 0.05).Conclusion Parecoxib 40 mg injected intravenously at 30 min before anesthesia can reduce the intrapulmonary shunt during one lung ventilation in patients undergoing esophageal cancer resection.
