Background: In laparoscopic cholecystectomy (LC), the extent of hemodynamic changes associated with creation of pneumoperitoneum depends on the intra-abdominal pressure attained, volume of CO2 absorbed, and patient’s intravascular volume. In our study, we attempted to compare the hemodynamic and capnographic changes in the low pressure (<8mm Hg) and standard pressure (12-14mm Hg) LC.Methods: In this randomized case control study, Group A included patients undergoing Low pressure LC (<8mm Hg). In group B, Standard pressure LC (12-14mmHg) was performed. Both groups were evaluated for the hemodynamic and capnographic changes and other parameters.Results: Difference in mean heart rate of Group A and Group B was found to be statistically significant at 10 min after induction. After 30 minutes of surgery, systolic blood pressure of Group B was found to be higher than that of Group A (p <0.05). Differences in diastolic blood pressure among patients of Group A and Group B were found to be statistically significant only at 30 min and 40 min after induction. Except at 30 min after induction, differences in EtCO2 levels of patients of Group A and Group B were found to be statistically significant.Conclusions: It appears that low pressure pneumoperitoneum appears to be having fewer effects on blood pressure- both systolic and diastolic, as compared to standard pressure pneumoperitoneum in patients undergoing LC. It also appears to be causing fewer derangements in ETCO2. This may help in smooth recovery and less post-operative problems.

Laparoscopic cholecystectomy is now gold standard and depends on good exposure of the peritoneal cavity. It is achieved by insufflation of the abdominal cavity with CO2. Operating at lower intraabdominal pressure (<12 -15mmHg) has been associated with fewer pulmonary and hemodynamic complications and lesser postoperative pain. Objective: To ascertain the advantages of low pressure pneumoperitoneum over standard pressure pneumoperitoneum Methods: Our study was quasi experimental study conducted at  KRL Hospital, Islamabad over period of 3years from 2013 to 2016. SPSS version 20 was used to calculate p value.  Results: A total of 456 patients of gallstones were equally divided in two groups assigned to undergo low pressure (7-8mm of Hg) pneumoperitoneum or standard pressure (12-14mm of Hg) pneumoperitoneum laparoscopic cholecystectomy The average age of patients was 46.2+/-13.6yrs in group A compared to 43.5 +/- 12.9 in group B. There were 60 (26.3%) male and 168 (73.7%) female patients in group A compared to 53 (23.2% and 175 (76.85) in group B respectively. It was found that group A 14 (6.1%) had no pain, 26 (11.4%) had VAS between 1 – 7 and 188 (82.5%) had VAS of 8 – 10 where as in group B 164 (72.6%) patients reported no shoulder tip pain postoperatively, 42 (18.6%) had VAS of 1 – 7 and 20 (8.8%) had VAS OF 8 – 10. The difference was statistically significant (p-value = <0.001). Conclusions: reduced pressure of pneumoperitoneum to 7 – 8 mm of Hg produce lower incidence of postoperative shoulder tip pain.

Introduction:- Insufation of carbon dioxide during laparoscopic cholecystectomy carries on to postoperative shoulder tip pain. The beginning of shoulder pain is commonly presumed to be due to overstretching of the diaphragmatic muscle bres due to high carbon dioxide pressure. Methods: - Patients came and admitted to the surgery department for elective cholecystectomy were enrolled in the study. The patients were randomly divided in two groups (group A and group B). In group A - low-pressure pneumoperitoneum (8 mm Hg) and in group B- standard pressure pneumoperitoneum (14 mm Hg) was created during laparoscopic cholecystectomy. Postoperative shoulder tip pain was evaluated at 4 hours and 24 hours after the operation. Results:- Fourteen patients or 28 % of patients in group B complained of postoperative shoulder tip pain as collated to only ve patients (10%) in group A. The mean intensity of postoperative shoulder tip pain assessed by the visual analogue scoring scale at 4 hours and 24 hours was less in group A as collated to group B. However, statistical signicance was seen only at four hours. Analgesic requirements and the mean length of postoperative stay in the hospital were minor in group-A as collated to group B. Conclusion: - Low-pressure laparoscopic cholecystectomy signicantly reduces the frequency and intensity of postoperative shoulder tip pain. Low-pressure laparoscopic cholecystectomy decreases the demand for postoperative analgesics, decreases postoperative hospital stay, and improves the quality of life in the initial stage of postoperative rehabilitation.

Background: Laparoscopic cholecystectomy is gold standard treatment for cholelithiasis now a days. Post-operative shoulder tip pain is common complain after laparoscopic cholecystectomy. The cause of this shoulder tip pain is multifactorial e.g. peritoneal stretching and diaphragmatic irritation. The main cause of this shoulder tip pain is pneumoperitoneum caused by carbon dioxide. Correlation of shoulder tip pain in case of low pressure (7-8 mmHg) and standard pressure (12-14 mmHg) pneumoperitoneum post laparoscopic cholecystectomy.Methods: A prospective randomized study was done in 100 patients of cholelithiasis in SMS hospital Jaipur Rajasthan. The patients were divided into two groups-Group A patients undergoing laparoscopic cholecystectomy at low pressure (7-8 mmHg) and group B patients undergoing laparoscopic cholecystectomy at standard pressure (12-14 mmHg). The intensity of shoulder tip pain were measured by visual analogue score at 1, 6, 12, 24 and 48 hours. In both of the group results were compared in terms of frequency of pain, intensity of pain and requirement of post-operative analgesics. The duration of hospital stay was also compared.Results: Post-operative shoulder tip was found to be less in low pressure group (group A) as compare to standard pressure group (group B). Total requirement of post-operative analgesic dose and hospital stay was also found to be less in low pressure group as compared to standard pressure group. This was statistically significant (p value<0.05).Conclusions: There is less intensity, frequency of shoulder tip pain, less post-operative analgesics requirement and less post-operative hospital stay after laparoscopic cholecystectomy done under low pressure pneumoperitoneum (7-8 mmHg).

Abstract Introduction Recent studies have shown that patients may experience considerable pain after laparoscopic cholecystectomy as well. Hence, this study was done to compare results on post op pain with low pressure pneumoperitoneum compared with standard pneumoperitoneum. Method 100 patients were selected for study and equally divided in two groups randomized into Low pressure (n = 50) and Standard pressure (n = 50). Operative time (min), postoperative pain (VAS) and frequency of Shoulder Tip Pain was noted in both groups Results A total of 100 patients were enrolled for this study. Patients were divided into two groups i.e. Group-A (Standard pressure) and Group-B (Low pressure). In group-A, there were 35(70%) males and 15(30%) females, while in group-B, there were 41(82%) males and 9(18%) females. Mean age of group-A patients was 42.0±7.0 years and 44.5±8.1 years in group-B. In group-A, 18(36%) patients had shoulder tip pain, while 4(8%) patients had had shoulder tip pain in group-B patients with a p-value of 0.001, which is statistically significant. Conclusions Laparoscopic cholecystectomy using low pressure pneumoperitoneum is feasible and results in less post-operative shoulder tip pain.

A prospective case control study was conducted at Medical College, Kolkata with the aim of evaluating the role of isoflavone( a class of phytoestrogen –plant compounds having the beneficial effects of estrogen but lesser risks and side effects) in postmenopausal women. 100 postmenopausal women (those who underwent total abdominal hysterectomy and bilateral salpingooopherectomy for different benign indications, aged between 40-50 years and who were menstruating before operation) were alternately distributed into two groups-Group A (n=50, received 60mg of isoflavone and 500mg of calcium per day for 6 months) and Group B (n=50, received 500mg of calcium per day only for 6 months). To evaluate the menopausal symptoms, the menopausal Kupperman index questionnaire was applied. Other outcomes measured were body mass index, blood pressure and lipid profile. Menopausal symptoms in Group A(those using isoflavones) were lower compared to Group B. The present study showed that Kupperman index decreased significantly in Group A (from 28.48 ± 2.03 to 16.32 ± 1.06 i.e. 45% decline) compared to Group B (from 24.56 ± 1.52 to 18.44 ± 1.11 i.e. 25% decline). No differences in blood pressure or body mass index were found during treatment between the two groups. . In our study total cholesterol, triglycerides and low-density lipoproteins (LDL) decreased significantly in Group A compared to Group B. Therefore our clinical study indicates that isoflavone can be an invaluable resource for postmenopausal women for combating menopausal symptoms.

Under treatment of postoperative pain has been the topic of several recent editorials. The prevention, recognition, and management of postoperative pain in adults, as well as in children, have been receiving a great deal of interest. The poor outcome obtained with current regimens is primarily due to the inadequacies of drug administration techniques rather than the qualities of opioids themselves. In this prospective study comparison of preemptive use of diclofenac, ketorolac and tramadol was done for postoperative pain in laparoscopic cholecystectomy. 60 patients were divided into three groups. Group A received injection Diclofenac (3mg/kg) 75mg maximum at a time. Group B received injection Ketorolac (30 mg). And group C patients received injection Tramadol (100 mg). All drugs were given intravenous half an hour before induction. Analgesic efficacy was measured in VAS scale. In addition pulse, systolic blood pressure, diastolic blood pressure, mean blood pressure, total pethidine requirement and time of first pethidine requirement were recorded Patients received an increment of 10-20 mg of pethidine when pain score was 3-4. In this study, total pethidine consumption in group A is 56.5±5.14, in group B is 46.75±4.65 and in group C is 49±5.42. It shows that group B and group C have same analgesic effectiveness and which is better than group A. On the basis of present prospective clinical study postoperative pain can be managed by preemptive use of diclofenac, ketorolac and tramadol. The analgesic efficacy of ketorolac and tramadol is same and better than diclofenac. Key Words: Pre-emptive analgesia, Laparoscopic cholecystectomy.

Objectives. Inspiratory, hemodynamic and metabolic changes occur in laparoscopic surgery depending on pneumoperitoneum and patient position. This study aims to evaluate the effects of intra-abdominal pressure increase based on CO2 pneumoperitoneum in laparoscopic operations on hemodynamic parameters and respiratory dynamics and satisfaction of surgeon and operative view.Materials and Methods. A total of 116 consecutive, prospective, ASA class I–III cases aged 18–70 years undergoing laparoscopic cholecystectomy were enrolled in this study. Data of 104 patients were analysed. Patients were divided into two groups as the group Low Pressure (<12 mmHg) (Group LP) (n=53) and the group Standard Pressure (>13 mmHg) (Group SP) (n=51). In this study administration of general anesthesia used total intravenous anaesthesia in both groups. All groups had standard and TOF monitorization applied. The anaesthesia methods used in both groups were recorded. Before, during and after peritoneal insufflation, the peroperative ventilation parameters and hemodynamic parameters were recorded. The adequacy of pneumoperitoneum, gastric and the operative view were evaluated by the operating surgeon and recorded.Results. The peripheral oxygen saturation showed no significant difference between the low and standard pressure pneumoperitoneum in view of tidal volume, respiratory rate, end tidal CO2, mean and peak inspiratory pressure, and minute ventilation values. In terms of hemodynamics, when values just after intubation and before extubation were compared, it was observed that in the LP group systolic, diastolic and mean blood pressure values were higher. In terms of heart rate, no significant difference was observed in determined periods between groups. There was no significant difference between the groups in terms of surgical satisfaction and vision.Conclusion. Low pressure pneumoperitoneum provides effective respiratory mechanics and stable hemodynamics for laparoscopic cholecystectomy. It also provides the surgeon with sufficient space for hand manipulations. Anaesthetic method, TIVA and neuromuscular blockage provided good surgery vision with low pressure pneumoperitoneum.

Abstract Background:The numbers of elderly persons have greatly increased worldwide due to improvement of medical health. Elderly complains of cardiopulmonary diseases and the incidence of emergent gall bladder diseases increase with age. Laparoscopic cholecystectomy is the usual approach in dealing with cholithiasis that greatly replace open approach even in acute emergency gall bladder diseases.Aim: compare between initial Fundus first cholecystectomy followed by Calot dissection VS Calot first cholecystectomy in Emergency laparoscopic cholecystectomy with low pressure pneumo-peritoneum in cardiopulmonary risk patients as regard intraoperative data and postoperative complications.Patients and methods:This prospective randomized controlled study was carried out in the Department of Emergency General Surgery on 470 cases with acute cholecystitis, biliary colic, mucocele and pyocele of gall bladder. The patients were divided into two groups, Group A: fundus-Calot group (235cases) and Group B (235cases): classical Calot first approach.ResultsIn most cases of group A, the operating time was up to 90 minutes, while in group B, most cases were more than 90 minutes. Intraoperative bleeding, visceral injury and biliary injury were higher in group B than in group A and therefore the conversion was higher in group B than in group A (14% vs. 4%). Postoperative sequelae were reported to be greater than in group B in regard to bleeding, biliary leakage and wound infections. Remote complications were more pronounced for biliary restrictions in Group B (14%) than in Group A (2%)Conclusion:Laparoscopic low-pressure pneumoperitoneum cholecystectomy with initial Fundus first method is an excellent and safe approach in treating acute gallbladder diseases in cardiopulmonary risk patients.

Background: Acute postoperative pain is a significant cause of morbidities. This study aimed to evaluate the effect of intraoperative blood pressure during laparoscopic cholecystectomy under general anesthesia on postoperative pain in patients without underlying disorders. Methods: In this randomized clinical trial, 72 patients undergoing general anesthesia for elective laparoscopic cholecystectomy were randomly assigned into two groups: Group A with higher than baseline preoperative blood pressure (MAP allowed to increase up to 20% higher than baseline MAP by inducing pneumoperitoneum) and group B with normal to low blood pressure (MAP deliberately controlled at a tight limit from normal baseline MAP values to 20% less than baseline by titrating TNG infusion). The Visual Analog Scale (VAS) after 2, 8, 12, and 24 hours of surgery, and the total dose of meperidine used to manage postoperative pain were recorded and compared between the two groups. Results: The pain scores in group A were significantly lower than group B (P = 0.001). The postoperative analgesia request time was different between the two groups (P = 0.53). During the first 24 hours, the total meperidine consumption dose in group A was significantly lower than in group B (P = 0.001). Conclusions: High intraoperative blood pressure may affect the postoperative pain after laparoscopic cholecystectomy and lead to less postoperative pain score and analgesic requirements.

The present study was done to evaluate the ability of oral pregabalin to attenuate the pressor response to airway instrumentation in patients undergoing laparoscopic cholecystectomy under general anesthesia. Sixty-four adult patients aged between 25-55 year of either gender belonging to ASA-1 or ASA2 physical status weighing 50-70 kg were enrolled in this study. Thirty-two patients each were randomized to group A, or group B. Patients in group A received tablet Pregabalin (150mg) and those in group B received placebo orally one hour before induction of anaesthesia. Heart rate, blood pressure, and sedation were assessed preoperatively before giving the tablets and after 30 minutes, and just before induction of anaesthesia. Intraoperative, pulse rate, mean arterial pressure, ECG in the lead II, SPO2 and ETCO2 were monitored. All the above parameters were noted during laryngoscopy and intubation, 3 minutes after CO2 insufflation, and then at every 10-minute interval till the end of surgery. These parameters were also recorded after extubating the patient. The Ramsay sedation scale was used to assess the sedation at the baseline, one hour after drug intake , one hour after extubation and 4 hour after surgery. Any adverse effects in the postoperative period were recorded. The result of our study shows that pre-emptive administration of oral pregabalin 150 mg significantly reduced the pressor response at the time of laryngoscopy and intubation, after CO2 insufflation and just after extubation. We conclude that oral pregabalin premedication is effective in successful attenuation of hemodynamic pressor response to laryngoscopy, intubation and pneumoperitoneum in patients undergoing laparoscopic cholecystectomy
