ABSTRACT
Objective To evaluate the effect of aminophylline on the efficacy of extubation under ultra-fast track anesthesia ( UFTA) in pediatric patients with congenital heart disease ( CHD) undergoing surgical correction of anomaly. Methods Ninety American Society of Anesthesiologists physical status Ⅰor Ⅱ pediatric patients, aged<6 yr, undergoing surgical correction of anomaly, were randomized into 3 groups ( n=30 each) using a random number table method: group Ⅰ, group Ⅱ and group Ⅲ. After the end of surgery, normal saline was given in groupⅠ, 1 mg∕kg aminophylline was given in groupⅡ, and 2 mg∕kg aminophylline was given in groupⅢ. The condition of extubation in the operating room and respirato-ry rate at extubation were recorded. Mean arterial pressure, heart rate and bispectral index value were re-corded at the end of surgery, and at 9 and 15 min after administration. Results Compared with groupⅠ, the rate of successful extubation in the operating room, BIS value at 9 min after administration and respira-tory rate at extubation were significantly increased inⅡand Ⅲ groups ( P<0. 05) . There was no significant difference in the parameters mentioned above between group Ⅱand group Ⅲ ( P>0. 05 ) . Conclusion Aminophylline can increase the efficacy of extubation under UFTA in pediatric patients with CHD undergoing surgical correction of anomaly, and 1 mg is the recommended dose.
ABSTRACT
Objective: Compared with ketamine anesthesia, to investigate sevoflurane inhalation combining laryngeal mask airway for anesthesia induction in pediatric cardiac surgery. Methods:A total of 40 pediatric patients with congenital heart diseases received elective cardiac surgery in our hospital from 2013-08 to 2014-01 were studied. The children were from 6 months to 2 years of age and randomly divided into 2 groups, n=20 in each group. Sevolfurane group, the children inhaled the mixture of 8%sevolfurane and 100%O2, laryngeal mask airway was used upon losing consciousness for mechanical ventilation, the anesthesia was maintained by (3-4)% sevolfurane inhalation to facilitate central venous catheter placement. Ketamine group, the children received intramuscular injection of ketamine (7 mg/kg)+atropine (0.01 mg/kg). The peripheral venous line was established upon losing consciousness, the intravenous midazolam (0.1 mg/kg), pipecuronium (0.10 mg/kg), fentanyl (5 μg/kg) were applied, then tracheal intubation was performed for mechanical ventilation and the anesthesia was maintained by (0.5-1)%sevolfurane to facilitate central venous catheter placement. Results: Sevoflurane group had the shorter time for losing the consciousness than that in Ketamine group (48.90 ± 3.93) s vs (577.85 ± 116.41) s, P0.05. The arterial PH value, PaCO2, BE and lactatein were similar between 2 groups, P>0.05. Conclusion: Sevoflurane inhalation combining laryngeal mask airway could shortening anesthesia preparation time with simple management. It provided an important anesthesia option in pediatric cardiac surgery.
ABSTRACT
Objective To investigate the efficacy of pancreaticoduodenectomy (PD) combined with vascular resection and reconstruction.Methods The clinical data of 56 patients who received PD combined with vascular resection and reconstruction at the Southwest Hospital of Third Military Medical University from January 2007 to May 2011 were retrospectively analyzed.The incidence of perioperative complications,mortality and postoperative conditions were also analyzed.Results The mean operation time and intraoperative blood transfusion were 473 minutes (range,234-853 minutes) and 781 ml (range,0-900 ml),respectively.Seven patients did not receive blood transfusion.The median period of hospital stay was 25.9 days (range,17-100 days).A total of 43 patients underwent PD combined with vascular reconstruction.The incidence of perioperative complications and mortality rate were 34％ (19/56) and 7％ (4/56),respectively.There were 42 patients with pancreatic ductal adenocarcinoma,5 with ampullary carcinoma,3 with distal bile duct carcinoma,4 with papillary carcinoma of duodenum,1 with pancreatic neuroendocrine carcinoma and 1 with pancreatic serous cystadenoma.All patients were followed up till August 2011,and the 1-year survival rate was 57％ (32/56).The mean survival time was 13.5 months.The weight of 32 surviving patients increased and no abdominal pain occurred.Within 3 months after the operation,5 patients had slight diarrhea and were administered antidiarrheal; thrombosis in the artificial blood vessels and peritoneal effusion were found in 1 patient,while 6 months later,collateral circulation was formed and the peritoneal effusion was diminished.Conclusion PD combined with vascular resection and reconstruction can improve the quality of life for patients with pancreatic cancer and with blood vessels involvement.
ABSTRACT
In the process of the introduction of classical problem based learning,the combination of PBL teaching method and current teaching method was found to be abstract and difficult to operate. PBL gradual teaching was brought forward through qestionnaires and analysis. Improved PBL teaching is more suitable for clinical teaching of hepatobiliary surgery in China and helping the interns to get good learning habits. Thus ,it is an effective PBL teahcing method of hepatobiliary surgery.
