BACKGROUND/AIM Anesthesiologists have encountered various difficulties in securing the airway. Therefore, we compare the intubation times and hemodynamic changes between the McGrath Series 5 video laryngoscope and the Macintosh laryngoscope. MATERIALS AND METHODS A total of 80 obstetric patients were divided into 2 groups, orotracheally intubated with either the McGrath video laryngoscope or the Macintosh laryngoscope. The intubation times, Cormack-Lehane grade, percentage of glottic opening, mean arterial blood pressure, and heart rates were compared among the groups. RESULTS Intubation time in the McGrath video laryngoscope group was significantly longer than in the Macintosh laryngoscope group (P <0.01). The percentage of glottic opening was found to be higher in the McGrath video laryngoscope group (P = 0.002). CONCLUSION The McGrath Series 5 video laryngoscope provides excellent views during orotracheal intubation in obstetric anesthesia with normal airways.

Objective: Lumbar spinal surgeries have been performed with either spinal or general anesthesia. In this study, we aimed to evaluate the superiority of either spinal or general anesthesia on one-level lumbar discectomies. Methods: After approval of Ethics Committee, we retrospectively analysed 328 patients those administered either spinal or general anesthesia for elective one-level lumbar discectomies over a two-year period. Patient records were reviewed to obtain demographic features, type of anesthesia, baseline heart rate, mean arterial pressure, intraoperative maximum heart rate and mean arterial pressure, duration in the operating room, amount of intravenous fluids, estimated blood loss, incidence of perioperative complications such as bleeding, nauseavomiting, hypotension and bradycardia, and postoperative analgesic consumption. Results: Patient characteristics including baseline/intraoperative mean arterial pressure and heart rate values did not differ between groups. However, the spinal anesthesia group experienced significantly shorter durations in the operating room and had a lower incidence of nausea-vomiting (p = 0.002 and p < 0.01, respectively). Analgesic comsumption in general anesthesia group was significantly higher than in spinal anesthesia group (p < 0.01). Conclusion: The present study revealed that spinal anesthesia is an effective alternative to general anesthesia in lumbar spinal discectomy.

Objective: In this study, we aimed to assess the perioperative and postoperative results of the patients who underwent bariatric surgery. Methods: After obtaining approval, a retrospectively designed observational study was conducted. All adult patients who underwent laparoscopic gastric plication, sleeve gastrectomy, or roux-en-Y anastomosis between January 2011 and May 2013 were included. Results: A total of 104 patients were included in the study period: 49 (47.1%) underwent laparoscopic roux-en-Y anastomosis, 44 (42.3%) underwent laparoscopic sleeve gastrectomy, and 11 (10.6%) underwent laparoscopic gastric plication. The present study showed a mortality rate of 1.9% (n = 2, one after Roux-en-Y anastomosis operation, and the other one after gastric plication). Conclusion: The anesthesia methods and approaches have no association with morbidity and mortality in such procedures of bariatric surgery indicated in the present study.

Objectives: To evaluate the possible value of the perfusion index (PI) as a tool for pain assessment. Methods: This prospective, observational study was performed with 89 patients underwent surgery with general anesthesia. The patients with visual analog scale (VAS)>3 were grouped as M1, and patients with VAS≤3 and performed morphine were grouped as M2. After surgery patients with VAS>3 were given 2mg morphine. Patients with VAS>3 were given increments of intravenous morphine (2 mg) at 20 minute intervals until VAS<3. The correlation and difference between PI and VAS score values were evaluated before and after analgesic administration. Results: Significant changes were found in both PI values and VAS scores between M1 and M2 groups (2.80±0.77, 3.97±0.94, p<0.001; 6.60±1.20, 2.74±0.46, p<0.001) Despite no correlation was found between PI values and VAS scores of M1 and M2 groups, weak negative correlation was detected between differences in PI values and VAS scores among groups (r=-0.255, p=0.016). Conclusion: Perfusion index is a parameter that can be used in the assessment of postoperative pain and responses to analgesics.

BACKGROUND AND OBJECTIVES A transversus abdominis plane block is a peripheral block method that has been used successfully for pain relief after total abdominal hysterectomy. However, the effects of the combination of the transversus abdominis plane block and general anesthesia on analgesic and anesthetic requirements remain unclear. This randomized placebo-controlled study is aimed to evaluate the effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy under general anesthesia. METHODS Sixty-six women undergoing total abdominal hysterectomy were randomized into two groups to receive general anesthesia alone (control group) or with transversus abdominis plane block using 20mL of 0.25% bupivacaine (transversus abdominis plane group). Intraoperative remifentanil and sevoflurane consumption were recorded. We also evaluated the postoperative pain, nausea, quality of recovery scores and rescue analgesic requirement during postoperative 24hours. RESULTS The total remifentanil and sevoflurane consumption is significantly lower in transversus abdominis plane group; respectively mean (SD) 0.130 (0.25) vs. 0.094 (0.02) mcg.kg-1.min-1; p<0.01 and 0.295 (0.05) vs. 0.243 (0.06) mL.min-1; p<0.01. In the postoperative period, pain scores were significantly reduced in transversus abdominis plane group soon after surgery; median (range) 6 (2-10) vs. 3 (0-5); p<0.001, at 2h (5 [3-9] vs. 2.5 [0-6]; p<0.001), at 6h (4 [2-7] vs. 3[0-6], p<0.001), at 12h (3.5 [1-6] vs. 2 [1-5]; p=0.003). The patients in the transversus abdominis plane group had significantly higher QoR-40 scores 190.5 (175-197) vs. 176.5 (141-187); p<0.001). CONCLUSION Combining transversus abdominis plane block with general anesthesia can provide reduced opioid and anesthetic consumption and can improve postoperative pain and quality of recovery scores in patients undergoing total abdominal hysterectomy.

The interscalene brachial plexus block (ISBB) is an effective procedure for minimizing postoperative opioid consumption and pain following arthroscopic shoulder surgery. The ultrasound (US)‐guided supraclavicular brachial plexus block (SCBB) seems to be an alternative technique for arthroscopic shoulder surgery. However, evidence is lacking regarding the impact of SCBB on postoperative pain management and recovery after arthroscopic shoulder surgery. The aim of this study was to compare the effects of SCBB with ISBB in terms of postoperative pain and quality of recovery after arthroscopic shoulder surgery.

OBJECTIVE: This study compares post-operative pain and analgesic consumption among patients who have undergone either an emergent or elective caesarean section. STUDY DESIGN: A total of 115 patients, comprised of 48 emergency caesarean section and 67 elective caesarean section patients, were enrolled in this prospective study. Pain intensity was evaluated with a numeric pain scale in the 1st, 2nd, 6th, 12th and 24th post-operative hours and total post-operative tramadol consumption within 24 hours was recorded for each patient. RESULTS: Total tramadol consumption for emergency caesarean section patients under general anesthesia was 222.91±56.52 mg and for elective caesarean section patients under general anesthesia was 181.71±55.38 mg (p 0.05). CONCLUSION: Analgesic consumption for emergency caesarean section patients under general anesthesia was observed to be high.

BackgroundThe optimal position for surgery is one in which the patient is provided the best possible surgical intervention and put at minimum risk. Different surgical positions may cause changes in tissue perfusion. This study investigates the relationship between surgical patient positions and perfusion index.MethodsA sample of 61 healthy individuals with no peripheral circulatory disorders, chronic diseases, or anemia was included in this study. Participants held six different positions: supine, prone, 45-degree sitting-supine, 45-degree supine with legs lifted, Trendelenburg (45-degrees head down), and reverse Trendelenburg (45-degrees head up). Perfusion index values were then measured and recorded after individuals held their positions for five minutes.ResultsParticipants’ perfusion index values were affected by different body positions (p < 0.05). Perfusion index was lowest in the sitting position (4.5 ± 2.5) and highest in individuals with Trendelenburg position (7.8 ± 3.8).ConclusionDifferent body positions can cause changes in tissue perfusion. This should be considered in patient follow-up along with the perfusion index.

OBJECTIVE Postoperative cognitive dysfunction (POCD) is common after anaesthesia in elderly patients. However, it may appear in patients of all ages. The main pathogenesis of cognitive dysfunction remains unclear, although there is some evidence that brain inflammation may alter cognitive abilities. In the present study, we aim to evaluate short-term and long-term effects of dexamethasone on cognitive dysfunction induced by sevoflurane anaesthesia in adult rats. METHODS Seven-month-old 30 male Wistar albino rats were randomised into three groups: sevoflurane group (exposure to sevoflurane), sevoflurane + dexamethasone group (exposure to sevoflurane and dexamethasone injection), and control group (exposure to 100% oxygen). Spatial learning and short-term (7 days after exposure) and long-term (30 days after exposure) memory were evaluated using Morris water maze test. RESULTS Sevoflurane induced significant deficit in spatial learning and short-term and long-term memory in adult rats. Dexamethasone-treated animals exposed to sevoflurane had equivalent performance as control animals in training and probe trials. CONCLUSION Sevoflurane may impair spatial learning and short-term and long-term memories in adult rats. The co-administration of dexamethasone and sevoflurane may ameliorate short-term and long-term cognitive dysfunctions induced by sevoflurane in adult rats.

OBJECTIVE The primary goal of the present study was to demonstrate the existence of a possible circadian variation in urgent operative deliveries. METHODS All urgent caesarean sections between 1 January 2014 and 1 January 2015 with known exact onset times of operation were included in this retrospective study. Cases that were previously scheduled for elective caesarean section were excluded. Information regarding age, delivery date, onset time of operation and type of anaesthesia was collected from the database. Analyses were completed using the Statistical Package for Social Sciences (SPSS Inc., Chicago, IL, USA) version 20.0 software. The statistical significance for all analyses was set at p<0.05. RESULTS A total of 285 urgent caesarean section deliveries were included in the study. There were 126 (44.2%) deliveries during the day shift and 159 (55.8%) during the night shift. 80 patients (28.1%) received general anaesthesia and 65 (22.8%) received spinal anaesthesia in the morning shift, whereas 54 patients (18.9%) received general anaesthesia and 86 (30.2%) received spinal anaesthesia during the night shift. CONCLUSION The present study suggested that urgent caesarean sections revealed a circadian rhythm during the day.
