Objective The aim of this study was to compare the effect of albumin infusion versus conservative therapy on both serum albumin concentration (SAC) and patient outcome in case of postoperative hypoalbuminemia after exploration laparotomy for major abdominal trauma. Patients and methods Sixty-four patients with major abdominal trauma who had undergone exploration laparotomy were studied. In addition to patient’s demographic data, serial postoperative SAC and intra-abdominal pressure up to the seventh day were measured. Moreover, clinical, laboratory, and radiological follow-up was conducted to evaluate the morbidity until patient discharge from the hospital. The mortality rate was also recorded. Results There were no significant differences between patients who received albumin (group A) for the treatment of hypoalbuminemia and those who did not receive albumin (group B) as regards length of ICU stay (P=0.33), first postoperative day SAC (P=0.99), total complications (P=1), and individual postoperative complications [hemodynamic instability with vasopressor requirement (P=0.74), abdominal compartment syndrome (P=1), multiple organ dysfunction syndrome (P=1), and anastomotic leak (P=1), acute respiratory distress (P<0.6), and mortality (P=1)]. However, SAC was significantly higher on the third, fifth, and seventh day postoperatively in group A than in group B (P<0.001). Conclusion Postoperative treatment of hypoalbuminemia in major abdominal trauma had no benefit as regards morbidity and mortality.","PeriodicalId":7492,"journal":{"name":"Ain-Shams Journal of Anaesthesiology","volume":"21 1","pages":"97 - 102"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77107873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the present study was to evaluate the effectiveness of the use of minimal ANH for blood transfusion requirements and re-opening in elective adult coronary artery bypass graft surgery using cardiopulmonary bypass. Patients and methods This prospective, randomized controlled study was conducted on 100 consecutive adult patients who underwent elective coronary artery bypass graft. Patients were randomly divided into two equal groups: the ANH group (n=50) and the control group (n=50). In the ANH group, 5–8 ml/kg of autologous blood was withdrawn after administering anesthesia and before systemic heparinization. Simultaneously, colloid solution (6% hydroxyethyl starch 130/0.4; Voluven) was infused in a ratio of 1:1, and then the blood was re-infused after bypass. Hemodilation was not carried out for the control group. Total amount of allogenic-packed red blood cell, fresh frozen plasma, platelet concentrate transfusion, and the number of patients undergoing re-opening because of excessive bleeding were calculated for the two groups. Results A significant decrease was observed in the number of red blood cell units and fresh frozen plasma transfusion per patient in the ANH group compared with the control group. Conversely, chest tube output, representing postoperative bleeding and platelet count, did not differ between the two groups. Conclusion In this study, the use of the minimal ANH technique reduced the consumption of allogenic red blood cells and fresh frozen plasma in adult cardiac surgery patients. However, this technique had no effect on postoperative bleeding, incidence of re-exploration, and platelet count.","PeriodicalId":7492,"journal":{"name":"Ain-Shams Journal of Anaesthesiology","volume":"92 1","pages":"3 - 9"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83752779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients and methods Sixty women aged 20–30 years, of American Society of Anesthesiology I–II, and with a single uncomplicated pregnancy were included in this study. Patients were randomly allocated to two equal groups: the spinal group received hyperbaric bupivacaine 0.5% at a dose of 1 ml plus 25 μg fentanyl (0.5 ml), whereas the epidural group received bupivacaine 0.25% at a 14 ml bolus dose with a background epidural infusion of bupivacaine 0.125% at 10 ml/h. Pain intensity was recorded on a visual analogue scale. The quality of pain relief was also related to patient satisfaction after delivery. Side effects such as hypotension, motor block, pruritus, sedation, and nausea were noted. Obstetric parameters and Apgar score were noted, and all results were compared. Results Onset of sensory block was earlier (5.6 ± 1.27 vs. 8.8 ± 1.62 min, P < 0.001) and visual analogue scale at 5, 60, 90, 120, and 150 min was lower in the spinal group compared with the epidural group. All these results were statistically signifi cant. Ninety percent of the parturients in the spinal group versus 62% in the epidural group scored the analgesic quality as excellent. No significant hemodynamic changes were recorded in either group. There were no significant differences between the two groups in motor block, sedation, and nausea. No cesarean section or instrumental delivery was performed. Oxytocin augmentation was needed in 33.3 versus 50% of the parturients in the spinal and epidural groups, respectively. Fetal heart rate disturbances were seen in 10% in the epidural group versus 6.6% in the spinal group. Apgar scores were high and no neonate had Apgar score less than 7 in either group. The overall cost was lower in the spinal group compared with the epidural group.

Pregabalin is a novel drug with a heightened research interest in the analgesic, sedative, anxiolytic, and opioidsparingeffects, invariouspainsettings, includingpostoperativepain.We investigated pregabalin analgesic efficacy in morbid obese patients experiencing acute pain after laparoscopic gastric bypass surgery and compared it with gabapentin and placebo. Patients and methods A randomized, placebo-controlled study was conducted on 90 morbidly obese patients undergoing laparoscopic gastric bypass surgery. Patients were allocated into one of the three groups; the pregabalin group in which the patients received 300mg pregabalin, the gabapentin group in which the patients received 1200mg gabapentin, or the control group in which the patients received placebo 2h prior to surgery. Postoperative pain was controlled with intravenous fentanyl via patient controlled analgesia (PCA). Fentanyl consumption over 24 h and pain intensity measured by visual analogue score at rest (static) and during cough (dynamic) at recovery time, 1, 2, 6, 12, and 24h were recorded. Also sedation status, somnolence, dizziness, headache, nausea, and vomiting were monitored. Results Postoperative 24 h fentanyl consumption was significantly higher in the control group compared with both pregabalin and gabapentin groups (P<0.001). Pain intensity on visual analogue score (static and dynamic) was significantly higher in the control group compared with both pregabalin and gabapentin groups at time of recovery, 1, 2, 6, 12, and 24 h postoperatively. Numeric sedation score was significantly lower in the control group compared with pregabalin and gabapentin groups at time of recovery, 1, 2, and 6h postoperatively. No significant differences were found among the three groups as regards somnolence, dizziness, headache, nausea, and vomiting.

Controlled hypotension, using a variety of pharmacological agents, during general anesthesia reduces blood loss and helps clear visibility of the surgical field during FESS. The aim of this study was to compare the surgical conditions for FESS during controlled hypotension provided by nitroglycerin (NTG) versus magnesium sulfate (MGS) under general anesthesia. Patients and methods Fifty adult patients of both sexes requiring FESS under general anesthesia were randomly divided to receive either NTG infusion of 3–5 µg/kg/min (group NTG, n=25) or MGS (group MGS, n=25) 30 mg/kg, administered as a slow intravenous bolus and 10 mg/kg/h by continuous infusion during the operation, to provide controlled hypotension. In both the groups, the mean arterial blood pressure was reduced until the targeted mean arterial blood pressure (55–65 mmHg) was achieved. Results Both drugs produced the desired hypotension, in the magnesium group there were better operative conditions, reduction in the duration of surgery (85.3±13.1 vs. 92.9±10.3 min) and reduced anesthetic requirements [average end-tidal sevoflurane concentration (vol %) and fentanyl consumption (μg); P<0.0001]. However, there was longer extubation time (10.0±2.9 vs. 5.5±2.3 min) and recovery time (16.7±4.4 vs. 9.8±2.3 min) in comparison with the NTG group. Heart rate values were significantly higher in the NTG group compared with the magnesium group (P<0.0004). Conclusion Both NTG and MGS can be used safely to provide controlled hypotension during FESS. However, MGS was better as it provided optimum surgical condition and less tachycardia.

Intraperitoneal injections of local anesthetics have been proposed to minimize postoperative pain after laparoscopic surgery. Patients and methods A total of 60 patients with American Society of Anesthesiologists status I and II aged 30–50 years undergoing elective laparoscopic cholecystectomy were divided into three equal groups (20 patients each): ultrasound-guided thoracic paravertebral block (UG-TPVB group) with 20 ml 0.25% bupivacaine bilaterally, intraperitoneal instillation of local anesthetics with 50 ml 0.25% bupivacaine after inflation of the abdomen with gas (IP group), and general anesthesia alone without any local anesthetics (GA group) (control group). General anesthesia was induced for all patients. Intraoperative and postoperative hemodynamic data (mean arterial blood pressure and heart rate) were recorded. Intraoperative anesthetic and analgesic consumption, pain intensity using visual analog scale, pethidine consumption, serum cortisol, blood glucose level, and complications were estimated.
