Opioid-free anesthesia with dexmedetomidine, lidocaine and propofol infusions may be an alternative technique for laparoscopic cholecystectomy especially in patients with high risk for postoperative nausea and vomiting.

SummaryThis study was designed to investigate the effects of desflurane on bronchial smooth muscle tone, following intubation and to compare these effects with isoflurane and sevoflurane. Patients were randomly divided into three groups to receive, isoflurane (n ¼ 22), sevoflurane (n ¼ 23), or desflurane (n ¼ 22). Peak inspiratory pressure (PIP), respiratory resistance (Rr) and dynamic compliance (Cdyn) measurements were recorded at three time points; After the beginning of ventilation and before inhalation agent was started, following 5 min of ventilation with 1 MAC (minimum alveolar concentration) inhalation agent and following 5 min of 2 MAC inhalation agent. We found that all inhalation agents caused a significant decrease in Peak Inspiratory Pressure (PIP) and respiratory resistance (Rr), and an increase in dynamic compliance (Cdyn) at 1 MAC concentrations. When the agent concentration was increased to 2 MAC, desflurane caused a significant increase in Rr and PIP and a decrease in Cdyn. We concluded that desflurane, like isoflurane and sevoflurane, exhibits a bronchodilator effect at 1 MAC concentration. However, increasing the concentration to 2 MAC caused an increase in airway resistance with desflurane, whilst sevoflurane and isoflurane continued to have a bronchodilator effect.

Purpose: In this study, the effects of intravenous paracetamol treatment on early postoperative period analgesia and recovery characteristics after laparoscopic cholecystectomy have been evaluated.Methods: Forty patients whose American Society of Anesthesiologists physical status I or II underwent laparoscopic cholecystectomy and randomly divided into 2 equal groups. In the first group, 1 g paracetamol was given to the patients intravenously after intubation before start of the surgery in 15 minutes. The 100 mL 0.9% NaCl was infused intravenously for the control group in 15 minutes. Postoperative pain was evaluated and recovery characteristics were evaluated.Results: Verbal and visual pain scores of the paracetamol group were significantly lower than control group (P<0.05). First morphine requirement and total administered morphine dose and duration of staying in recovery room were significantly decreased in the paracetamol group (P<0.05).Conclusions: Beside its effective analgesic properties, paracetamol administration during per operative period supports effective and faster recovery.

IVB injection as monotherapy seems to be a very effective treatment modality for ROP. Based on timely intervention, IVB as a single treatment modality can salvage almost all ROP cases before stage 4.

Pulse oximetry is a frequently used tool in anesthesia practice. Gives valuable information about arterial oxygen content, tissue perfusion and heart beat rate. In this study we aimed to provide the comparison of peripheral capillary hemoglobin oxygen saturation (SpO2) values among every finger of the two hands. Thirty-seven healthy volunteers from operative room stuffs between the ages of 18–30 years were enrolled in the study. They were monitored after 5 min of rest. After their non invasive blood pressure, heart rate, fasting time and body temperature were measured, SpO2 values were obtained from every finger and each of two hands fingers with the same pulse oximetry. All the SpO2 values were obtained after at least 1 min of measurement period. A total of 370 SpO2 measurements from 37 volunteers were obtained. The highest average SpO2 value was measured from right middle finger (98.2 % ± 1.2) and it was statistically significant when compared with right little finger and left middle finger. The second highest average SpO2 value was measured from right thumb and it was statistically significant only when compared with left middle finger (the finger with the lowest average SpO2 value) (p < 0.05). SpO2 measurement from the fingers of the both hands with the pulse oximetry, the right middle finger and right thumb have statistically significant higher value when compared with left middle finger in right-hand dominant volunteers. We assume that right middle finger and right thumb have the most accurate value that reflects the arterial oxygen saturation.

While sevoflurane induction and maintenance is a suitable anesthetic modality for obese patients, TIVA can be applied easily in those patients possessing no extra risk factors other than morbid obesity.

The use of LigaSure facilitates the dissection of mesoappendix and shortens the operation time in LA. We believe that LigaSure is a safe, useful tool for mesoappendix dissection.

The systemic inflammatory responses after laparoscopic SAGB were significantly reduced compared with those after open SAGB.
