Objective: This study aimed to evaluate the effect of serratus anterior plane block (SAP) on postoperative morphine consumption. We aimed to determine the differences between both similar blocks and evaluate the effect of the methods of application of this block on patients' postoperative pain scores and morphine consumption. Material and Methods:This study is a single-center, prospective and observational study performed with 40 volunteer patients with American Society of Anesthesiologists (ASA) I-III, who were 18-70 years of age, scheduled for breast surgery. A total of 40 patients who underwent general anesthesia were divided into two groups each with 20 patients. While SAP block was applied to the study group, no block was applied to the control group. SAP block was made by injecting a total of 40 ml of 0.25% bupivacaine between 2 muscles after the test dose was injected with saline. All patients were followed up for 12 hours postoperatively with patient-controlled analgesia (PCA) pump. Morphine consumption, visual analogue score (VAS) values and side effects were recorded at the postoperative 1 st , 6 th and 12 th hours.Results: There was no significant difference between the two groups in terms of hemodynamic parameters and demographic data. Postoperative morphine consumption and postoperative analgesic requirement were significantly lower in the SAP block group (p< 0.001). Postoperative VAS values were significantly lower in the SAP block group (p< 0.001). No complication was observed related to the block. Conclusion:It was found that the SAP block reduced morphine consumption, significantly decreased VAS values, and reduced side effects due to opioids postoperatively.

This study aims to investigate the organ donation rate, the causes of brain death and the blood gas parameters before and after apnea test by assessing the records of the patients with brain death diagnosis in the last five years in our hospital. Method: The records of 44 patients who were diagnosed as brain death between 01.01.2014-15.05.2019 at Cumhuriyet University Research and Application Hospital were retrospectively reviewed. Blood gas parameters before and after apnea test, demographic characteristics, educational status, duration of diagnosing brain death, distribution of the patients according to their services, organ donation rate, the causes of brain death were evaluated. Results: When the patients diagnosed with brain death in Cumhuriyet University Hospital between January 2014 and May 2019, 44 patients were found. Of these patients, 23 were female (52.3%) and 21 were male (47.7%). When the patients who were diagnosed with brain death were examined; 26 patients (59.1%) were found to be in the neurosurgery intensive care unit and 13 patients (29.5%) in anesthesia intensive care unit. When the causes leading to brain death are examined; The most common cause was subarachnoid hemorrhage (SAH) in 18 patients (40.9%). Of the 44 patients diagnosed with brain death, 9 (20.5%) were donors, and 35 (79.5%) were not donors. Conclusions: This retrospective evaluation of 44 patients diagnosed with brain death within five years in intensive care units of our hospital revealed that organ donation rates were below the national average. We think that not delaying in donor determination, not to be lack of donor care, training of health workers in brain death and organ donation will increase the awareness on organ donation and organ donation rates will increase in our hospital.

Introduction: Ultrasound (USG) guided supraclavicular block in upper extremity surgery is a popular approach. In recent years, many studies have been published on the perfusion index (PI) in the evaluation of block success. The main objective of this study is to evaluate the success and efficiency of the supraclavicular block with traditional methods (Pin-prick test, Modified Bromage Scale) and perfusion index. Materials and Methods: After the approval of the ethics committee (2018-11/01) was taken for the study; 30 volunteer patients who were 18-75 years old with American Society of Anesthesiologists (ASA) I-II scores undergoing a hand, forearm, arm surgery, were included in the study. In this prospective study; after ultrasound-guided supraclavicular block has been applied by injecting local anesthetic that consists of prilocaine 12.5 ml + bupivacaine 12.5 ml to all patients, sensory block was checked with pin-prick test every 3 minutes, motor block was checked by using modified Bromage scale every 2 minutes, hemodynamic parameters and PI values were recorded every 5 minutes. Times of motor block onset and total mot or block onset, sensory and motor block ending time, the duration of block technique, the time of first postoperative analgesia consumption and positivity time for pin-prick test were recorded. Results: When the measured perfusion index values were compared, the differences were significant. When we compared the PI values in pairs, the differences between basal and 5 th min, 10 th min, 15 th min, 20 th min, 25 th min, and 30 th min were significant. Positivity time for pin-prick test was 8.83 ± 2.70 min (minimum 5 minutes and maximum 15 minutes), motor block onset time was 6.7 ± 2.89 min (minimum 2 minutes and maximum 13 minutes), time of total motor block onset was 10.83 ± 3.07 min (minimum 6 minutes and maximum 19 minutes). In the 5 th minute PI values, an average increase of 148% was observed compared to basal PI values. Conclusion: As a result; the supraclavicular block provided faster sensory-motor block than other upper extremity blocks. It was concluded that the perfusion index was faster, more objective and simpler method than traditional methods in assessing the block success, due to vasodilatation that occurred before sensory and motor block.

E lectroconvulsive shock is applied to one or both cerebral hemispheres to initiate a seizure. Variables of this shock include stimulus pattern, amplitude and duration. The aim of electroconvulsive therapy (ECT) is to create a therapeutic generalized seizure for 25-60 seconds [1]. Routine use of general anesthesia to induce unconsciousness and to prevent the damage by neuromuscular blockade raised interest in ECT.Seizure activity is characteristically associated with prolonged sympathetic discharge following an initial parasympathetic discharge. The initial phase is characterized by bradycardia and increased secretion. Sometimes,

Objective: The present study aims to compare the clinical and laboratory characteristics of patients diagnosed with coronavirus disease (COVID-19) using Real-Time Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) and Computed Tomography (CT). Materials and Methods:In this study, 240 adult patients were included. The demographic data, symptoms, COVID-19 findings in the initial pulmonary CT during admission and the first laboratory parameters were recorded. The patients were divided into three groups as Group 1 consisting of 100 PCR (+) CT (+) patients, Group 2 consisting of 40 PCR (+) CT (-) patients, Group 3 consisting of 100 PCR (-) CT (+) patients. Results:The mean symptom duration was 5.78 days in Group 1, 2.67 days in Group 2, and 5.26 days in Group 3 (p<0.05). The mean symptom duration was 5.52 days in CT (+) patients and 2.67 days in CT (-) patients (p<0.05). The findings showed that one unit increase in pathological lobe count decreased PCR positivity by 1.3 times (p=0.002). Conclusion:There may not be any findings in CT in the first 48-72 hours after the onset of the symptoms in symptomatic patients, and as the number of pathological pulmonary lobes detected in CT increases, PCR positivity decreases.
