According to the high oncotic pressure of albumin along with prolonged half-life of its molecules in comparison to NS in the intra-vascular compartment, it has been proposed that a more significant reduction of the plasma viscosity might be expected after the infusion of albumin. Methods: A total of 56 patients referring to the general operating room for their elective minor surgeries were evenly divided into two groups (V1, V2). It was calculated that 28 patients were needed to be enroll in each study group to detect a difference as big as 0.15 millipoise (mPa.s) with a statistical power of 80%.  The V1 group received 1000 ml of NS but the V2 group received 1000 ml of recombinant albumin 5% in half NS within one hour, as fluid replacement therapy, during the intra-operative period. We have designed a simple measurement system according to Poiseuille’s formula by which the viscosity value could be measured reliably since the system was calibrated frequently using distilled water as a reference. Results: The mean value of the pre-operative plasma viscosity of the patients was 1. 73 ± 0.25 mPa.s and 1.76 ± 0.21 mPa.s in V1 and V2 groups respectively. After the infusion of the fluids, the mean viscosity values decreased to 1. 68 ± 0.30 mPa.s and 1.66 ± 0.17mPa.s in V1 and V2 groups respectively (p= 0.37). https://aacc.tums.ac.ir/index.php/aacc/article/view/5 https://aacc.tums.ac.ir/index.php/aacc/article/download/5/58

These complications can cause postoperative morbidity. This study was designed to determine the effect of ketamine spraying on the endotracheal tube cuff on sore throat, cough, and hoarseness during the first 24 hours of the postoperative period. Methods: 120 healthy women with term singleton pregnancy scheduled for elective term cesarean delivery under general anesthesia were enrolled. Patients were randomized into two equal groups. 1 ml (50 mg) ketamine was sprayed on the endotracheal tube cuff in group K as a study group and 1 ml normal saline was sprayed on the endotracheal tube cuff in group N as a control group. The patients were interviewed for sore throat, cough, and hoarseness at  1, 6 and 24 hours after general anesthesia. Results: In group K, no patient reported sore throat, cough and hoarseness in the first hours after surgery. However at the same time in group N the incidence of these symptoms was significantly higher than group K. The incidence of combined moderate and severe sore throat, cough and hoarseness was significantly lower in group K compared with group N, not only in 6 hours after surgery (1.67%, 0, 0 in group K vs 13.34%, 18.34%, 16.68% in group N, p<0.05) but also 24 hours after operation (1.67%, 0, 0 in group K vs13.3%, 16.6%, 11.67% in group N, p<0.05). Conclusion: Ketamine spraying on the endotracheal tube cuff reduces the incidence of sore throat, hoarseness and cough in patients undergoing operation under general anesthesia. https://aacc.tums.ac.ir/index.php/aacc/article/view/7 https://aacc.tums.ac.ir/index.php/aacc/article/download/7/178

Its prevalence is about 25-80% and is observed more commonly with rapid-acting volatile anesthetics than the older inhalation agents. Methods: 30 patients aging between 2 to 8 years were included in this randomized double blind study. We compared the effect of combination of two anesthetic drugs, Propofol-Ketamine and Sevoflurane- Ketamine, on ED and pain after general anesthesia in pediatric patients undergoing interventional cardiac angiography. Agitation was measured by PAED (Pediatric Anesthesia Emergence Delirium) scoring system) and pain by the CHEOPS (Children’s Hospital of Eastern Ontario Scale). Results: Emergence delirium in 10th minute of recovery was higher in propofol group (7.6±4.47 vs 5.07±3.31, p=0.047) but it was the same between the groups during the rest of recovery times. Pain scores were higher only at the moment of entrance to recovery room in sevoflurane group (6.27±1.99 vs 5.1±1.06, p<0.001). Mean recovery time was shorter in the sevoflurane group than in the propofol group (33.83±15.239 vs 51.67±20.585, p=0.02).  Nausea and vomitting was more frequent in the sevoflurane group (6.6% vs 0%, p, 0.001), which needed no treatment. Conclusion: There are some minor differences between sevoflurane-ketamine and propofol-ketamine anesthesia. If the length of recovery is not an issue and the patients are not at high risk of nausea and vomiting, either sevoflurane-ketamine combined anesthesia or propofol-ketamine infusion can be suitably used to anesthetise patients for the pediatric cardiac catheterization procedures. https://aacc.tums.ac.ir/index.php/aacc/article/view/10 https://aacc.tums.ac.ir/index.php/aacc/article/download/10/76

In this study we evaluated the effects of oral Tizanidine on the reduction of pain caused by spinal needle puncture and hemodynamic responses. Methods: In this double blind randomized clinical trial, 52 patients who were scheduled for elective surgeries under spinal anesthesia were recruited. They were randomly allocated in 2 groups of case and control. In the case group 4mg oral Tizanidine was administered to patients one hour before surgery while control group received placebo  Heart rate, systolic and diastolic blood pressure were recorded  exactly before spinal needle puncture and 1,3 and 5 minutes after spinal anesthesia. Results: The mean average of pain score was significantly lower in case group (p< 0.001). Also hemodynamic variables, in terms of heart rate and diastolic blood pressure, were statistically different between two groups (p=0.04 and p=0.02); however, the difference between systolic blood pressure was not significant between two groups. Conclusion: Premedication with 4mg oral Tizanidine produced stability in blood pressure and heart rate during surgery and reduced pain intensity caused by needle puncture. https://aacc.tums.ac.ir/index.php/aacc/article/view/18 https://aacc.tums.ac.ir/index.php/aacc/article/download/18/187

However, there is a controversy about this effect of ketamine especially if used in small dosage. We proposed to evaluate the hemodynamic effect of small dose of ketamine during Phacoemulsification. Methods: One hundred patients of ASA physical status I-III were chosen for this prospective, randomized, double-blind placebo-control study. Our patients were assigned randomly to two groups, ketamine group (n=50) and a control group (n=50).  After premedication, 0.15 mg/kg ketamine was injected intravenously in ketamine group. After three minutes Phacoemulsification was begun under topical anesthesia. The hemodynamic variables were recorded during the procedure and compared between two groups. Results: The systolic, diastolic and mean blood pressure were statistically significantly higher in the ketamine group (p<0.001) during the procedure. The heart rate during operation was higher in the ketamine group compared to control group (p<0.001). 46 (92%) patients in the ketamine group and 38 (76%) patients in the control group were satisfied according to surgeons (p=0. 001). Nausea and vomiting occurred at similar rates in each group. Also, hallucination and other psychological events did not occur in either of the groups. Conclusion: We found that systolic, diastolic, mean arterial blood pressure in patients who received small dose of ketamine were higher during the operation. https://aacc.tums.ac.ir/index.php/aacc/article/view/23 https://aacc.tums.ac.ir/index.php/aacc/article/download/23/194

Recently, the new definition of ARDS has been published, and this definition suggested severity-oriented respiratory treatment by introducing three levels of severity according to PaO2/FiO2 and positive end-expiratory pressure. Supportive care, principally with mechanical ventilation, remains the cornerstone of therapy from maintaining normal physiological parameters to avoiding ventilator-induced lung injury while providing adequate gas exchange. Basic elements of this strategy consist of avoiding lung overdistension by limiting tidal volumes and airway pressures, use of PEEP with or without lung recruitment maneuvers in patients with severe ARDS. This review focuses on changes in ARDS definition, epidemiology, clinical and basic research, and current and future directions in treatment. https://aacc.tums.ac.ir/index.php/aacc/article/view/24 https://aacc.tums.ac.ir/index.php/aacc/article/download/24/193

The exact cause of the degeneration is unknown. Loss of these cells results in a progressive lower motor neuron disease that has no sensory involvement and that is manifested as hypotonia, weakness, and progressive paralysis. Kugelberg Welander spinal muscular atrophy (also known as Wohlfart-Kugelberg-Welander syndrome or mild SMA) is a milder form of SMA, with symptoms typically presenting after age 18 months. Here in we report a case of anesthetic management of a patient with Kugelberg Welander disease who was refered for squint surgery and also we reviewed some other cases of SMA patients receiving different types of anesthesia. https://aacc.tums.ac.ir/index.php/aacc/article/view/25 https://aacc.tums.ac.ir/index.php/aacc/article/download/25/188
