ABSTRACT
Background and Aim: Anesthetic techniques are based on hemodynamic stability during anesthesia and surgery. Dexmedetomidine is centrally acting α2 agonist with sedative, sympatholytic and analgesic. Aim of this study was to compare effect of conventional dose with low dose infusion of dexmedetomidine on hemodynamic stress response, induction agent requirement & postoperative analgesia. Materials and methods: Single randomised prospective study done on 100 ASA Ι and ΙΙ patients aged 18-65 years scheduled for elective laparoscopy cholecystectomy under general anesthesia. Patients were divided in to two groups of 50 each, Group A: 1 µg/kg loading dose of Rolaniya SL, Dhawan S, Meera Kumari, Jain R, Pareek A, Sehtia S. Comparison of conventional dose and low dose infusion of dexmedetomidine on hemodynamic stress response, dose of induction agent and postoperative analgesia in patients undergoing laparoscopic cholecystectomy. IAIM, 2017; 4(7): 111-117. Page 112 dexmedetomidine I.V. started 15 min before procedure and infusion. 5 µg/kg/hr after induction and continued till end of surgery. Group B: 0.5 µg /kg/hr of dexmedetomidine I.V. started 15 min before procedure and continued till end of surgery. Results: Hemodynamic stability more in group B by avoiding complications like hypotension and bradycardia (p value < .05). Reduction of induction dose was more in group A than group B as compared to standard doses (P value <0.01). Hypotension and bradycardia were observed in 5 cases after 15 min of infusion in group A ( p value <.01). Mean VAS score in Group A was at 330 min was 3.10.39 and 3.150.94 at 210 min in group B. Conclusion: Low dose infusion of dexmedetomidine provides more hemodynamic stability. Requirement of induction agent was decreased more in group A than group B. Postoperative analgesia more in group A.
ABSTRACT
Objective To investigate the efficacy of laparoscopic cholecystectomy(LC)for patients with acute cholecystitis.Methods From May 2003 to November 2007,238 patients with acute cholecystitis underwent LC in our hospital.Four trocars were used in the operation.During the procedure,intraperitoneal pressure was controlled at 11 to 13 mm Hg(10 mm Hg for elderly patients).Retrograde cholecystectomy was performed on the patients with difficult anatomy caused by edema of the cystic triangle.For cases with calculi incarcerated in the cystic duct,the LC was performed after the stones were removed into the cyst(cholangiography was performed to exclude bile duct calculi).Results Of the 238 cases,LC was completed successfully in 220 patients,the other 18 cases were converted into open surgery because of massive hemorrhage and difficult anatomy(12 cases)or bile duct calculi(6 cases).After the LC,two patients received a second surgery because of postoperative hemorrhage;six patients developed bile leakage(occurred at 2-4 days after the LC with 50-80 ml of drainage)and were cured by conservative therapy including fasting,intravenous nutrition and anti-biotic therapy.This series were followed up for 1 to 12 months(mean,6 months).No post-operative complications were noticed during the period.Conclusions LC is a safe and effective for patients with acute cholecystitis or acute episode of chronic cholecystitis.Controlling the operation opportunity properly and dissecting the Calot's triangle area carefully to expose the cystic duct are the key steps during the operation.Convertion to open surgery is necessary in some difficult situations.
ABSTRACT
Introduction: The growing list of patients awaiting cholecystectomy, together with the great demand for beds and operating rooms at University Hospitals have encouraged the adoption of different solutions. Objective: To evaluate the process of organization and the clinical results of intensive programs of cholecystectomy by videolaparoscopy on an ambulatory surgery basis. Methods: Among the 314 patients with symptomatic cholelithiasis who were waiting for surgery at HCFMRP-USP, 160 were selected for treatment on an ambulatory basis. A multiprofessional team consisting of surgeons, anesthesiologists, nurses and social workers scheduled 4 intensive programs to be performed on weekends according to the availability of the surgical block and of the post-anesthesia recovery room. In a retrospective evaluation, the authors analyzed 79 medical records of patients operated upon in the intensive programs I and II (Group A) and 79 records of the 80 patients operated upon in the intensive programs III and IV (Group B). Statistical analysis was concluded using the Wilcoxon and Fisher's exact tests, with the level of significance of p=0.05. Results: Co-morbidities were recorded for 48 patients of Group A (60.8%) and for 31 of Group B (39.8%), p=0.007. Acute inflammation and scleroatrophy of the gallbladder were observed in 10 patients of group A (12.7%) and in 2 patients of group B (2.6%). The mean duration of surgery was 90 minutes (25-240) for group A and 68.2 minutes (20-180) for group B, p=0.002. There was one conversion in each group (1.3%). Prophylaxis for pain and vomiting was performed in 13 (16.4%) and 2 (2.5%) patients of group A, respectively. In group B, 63 patients (79.7%) received prophylaxis with analgesics and 73 (92.5%) with anti-emetics. Abdominal pain, vomiting and cardiorespiratory symptoms during post-anesthetic recovery involved 34 (43%), 18 (22.6%) and 10 (12.6%) of the patients in group A and 18 (22.8%), 14 (17.7%) and 3 (3.8%) of the patients in group B. The need for an overnight stay was greater in group A: 45 patients (50.7%) with a mean hospital stay of 18.3 hours (2.2-26), while in group B 5 patients stayed overnight and the mean permanence time was 7.8 hours (4-24), p=0.000. Five hospital admissions occurred in group A (6.3%) and 2 in group B (2.5%). Medical re-evaluation during the first week was necessary for 8 patients of group A (10.2%) and resulted in 3 readmissions (3.8%). In group B, 2 patients (2.6%) sought health services but did not require readmission. In group A, 2 patients presented coliperitoneum and 1 was re-operated upon. No death occurred in either group. Conclusion: As experience was gained in these programs, the process of patient selection and the offer of preoperative care were improved, demonstrating that intensive programs of videolaparoscopic cholecystectomy are a possible strategy for the reduction of waiting lists.
Introdução: As listas de espera para colecistectomia, associadas à elevada demanda dos leitos e salas cirúrgicas dos Hospitais Universitários, são incentivos para adoção de novos programas de assistência. Objetivo: Avaliar o processo de organização e os resultados clínicos dos Mutirões de Colecistectomia por Videolaparoscopia, em regime de Cirurgia Ambulatorial. Pacientes e Métodos: Dentre os 314 pacientes portadores de colelitíase sintomática que aguardavam cirurgia no HCFMRP-USP, 160 foram selecionados para tratamento em regime ambulatorial. Uma equipe multiprofissional, formada por cirurgiões, anestesistas, enfermeiros e assistentes sociais, programou 4 mutirões para serem realizados em fins de semana, em função da disponibilidade do bloco cirúrgico e da sala de recuperação pós-anestésica. Mediante avaliação retrospectiva, foram analisados 79 prontuários dos pacientes operados nos Mutirões I e II (Grupo A) e 79 dos 80 operados nos Mutirões III e IV (Grupo B). Análise estatística: teste de Wilcoxon e exato de Fisher (p 0,05). Resultados: As co-morbidades foram registradas em 48 pacientes do Grupo A - (60,8%) e em 31 do Grupo B (39,8%) (p=0,007). A inflamação aguda e a escleroatrofia da vesícula foram observadas em 10 pacientes do Grupo A (12,7%) e em 2 do Grupo B (2,6%). A duração média das operações, em minutos, foi de 90 (25-240) no Grupo A e de 68,2 (20-180) no Grupo B (p=0,002). Houve uma conversão em cada Grupo (1,3%). A profilaxia da dor e dos vômitos foi realizada, respectivamente, em 13 (16,4%) e em 2 (2,5%) pacientes do Grupo A. No Grupo B, 63 pacientes (79,7%) receberam analgésicos e 73 (92,5%) antieméticos de forma profilática. A dor abdominal, os vômitos e os sintomas cardiorespiratórios, na recuperação pós-anestésica, acometeram, respectivamente, 34 (43%), 18 (22,6%) e 10 (12,6%) dos pacientes do Grupo A e 18 (22,8%), 14 (17,7%) e 3 (3,8%) do Grupo B. A necessidade de pernoite foi maior no Grupo A: 45 pacientes (50,7%) com permanência hospitalar média de 18,3 horas (8,2-26), enquanto no Grupo B houve 5 pernoites e a média de permanência foi de 7,5 horas (4-24) (p=0,000). Ocorreram 5 internações no Grupo A (6,3%) e 2 no Grupo B (2,5%). A reavaliação médica, na primeira semana, foi necessária em 8 pacientes do Grupo A (10,2%) e redundou em 3 readmissões (3,8%). No Grupo B, 2 pacientes (2,6%) procuraram o serviço de saúde e a readmissão não foi necessária. No Grupo A, 2 pacientes apresentaram coleperitônio e 1 foi reoperado; não houve óbitos em nenhum Grupo. Conclusão: O aprimoramento no processo de seleção e nos cuidados perioperatórios para colecistectomia videolaparoscópica, em regime ambulatorial, assegura o tratamento, na forma de mutirões, como estratégia eventual de redução das listas de espera.

ABSTRACT
BACKGROUND: Laparoscopic cholecystectomy is of benefit to reduce postoperative pain but many patients suffer from considerable pain after the surgery. The aim of this study was to investigate whether the preoperative infiltration of bupivacaine at the trocar site reduced the intensity of the postoperative pain or not. METHODS: Sixty patients who underwent elective laparoscopic cholecystectomy were selected. In a randomozed study, patients were divided into three groups. General anesthesia was induced with pentothal and succinylcholine, and maintained with vecuronium and isoflurane. After induction, the preincisional group (n = 20) received 0.25% bupivaciane 20 ml infiltration before skin incision and the postoperative group (n = 20) was given 0.25% bupivacaine 20 ml after peritoneal closure. The control group (n = 20) did not receive bupivacaine at any time. The first time of demand for analgesics and the amount of analgesics given during postoperative 48 hours were checked and recorded. The degree of postoperative pain was assessed hourly by visual analogue scale (VAS) score until 9 hours and checked once more at 24 hours postoperatively. RESULTS: The first times of demand for analgesics were significantly delayed in the preoperative group (12.1+/-6.0 hours) as compared with the control (2.9+/-1.6 hours) and postoperative groups (6.2+/-3.9 hours). The demand for analgesics until 9-hour postoperation by the preincisional group (10.5+/-14.7) was significantly less than that of the control (42.0 20.4) and postoperative groups (31.5+/-22.8). The VAS score of the preoperative group was lower than that of the control or postoperative groups during the postoperative 24 hours. CONCLUSIONS: Local infiltration of 0.25% bupivacaine into the trocar site preincisionally could reduce the early postoperative pain after laparoscopic cholecystectomy.

Objective To report on the experiences related to diagnosing and managing the bile duct injury in laparoscopic cholecystectomy. Methods To analyse retrospectively the diagnostic and treating experience in 23 cases of bile duct injury. Results Twelve cases of the common bile duct injury, 6 cases of transection of common bile duct, 2 cases of transection injury of common hepatic duct, one case of transec-tion of right hepatic duct, one case of transverse clip block of common bile duct, perforation in each of common bile duct and common hepatic duct. Eleven cases of accessory hepatic duct injury, including one case of aberrant bile duct injury, 7 cases of tiny accessory hepatic duct injury and 3 cases of thick accessory hepatic duct injury. All cases in this group were cured. Conclusion Comparing with LC and open cholecystectomy, occult bile duct injury is more readily to happen in LC with more difficulty in repairment and poor prognosis. Therefore we should strictly select the appropriate operative manual according to patient' s situation.
ABSTRACT
During the laparoscopic cholecystectomy, the ventilatory and hemodynamic changes could occur due to the peritoneal insufflation of CO2 as well as the position change. Various sults of the relationship between arterial and end-tidal PCO2 in different conditions have been reported. The authars studied to determine how closely end-tidal PCO2 reflects arterial PCO2 before, during, and after laparoscopic cholecystectomy. Peak inspiratory airway pressures, arterial blood pressures and heart rates were also measured simultaneously. Peritoneal insufflation of CO2 resulted in significant increase in peak inspiratory airway pressure and arterial blood pressure, but there were no significant changes in heart rates. Arterial and end-tidal PCO2 increased during laproscopy and, although there was no statistical significance in P(a-ET)CO2, P(a-ET)CO2 increased during laparoscopy and retumed to perinsufflation level after deflation of CO2. There was positive correlation between arterial and end-tidal PCO2 before CO2 insufflation, 10 minutes after CO2 insufflation and 10 minutes after deflation of CO2. However there was no correlation at 30 and 50 minutes after CO2 insufflation. These results suggested that the arterial PCO2 could not reflect end-tidal PCO2 exactly, and intermittent arterial blood gas studies should be warranted during laparoscopic cholecystectomy.
