Background/aim: Ultrasonographic measurements of inferior vena cava (IVC) diameters and right ventricle (RV) volumes are important tools for the evaluation of intravascular volume. The current study investigates the association of IVC diameters and RV volumes before colonoscopy in prediction of postanesthesia hypotension., Materials and Methods: Seventy patients scheduled for colonoscopy were included in the study. Preoperatively, expirium (dIVC max) and inspirium (dIVC min) IVC diameters were measured using M-mode ultrasonography and the collapsibility index (IVC-CI) was calculated. Ventricular volumes and areas were also measured using transthoracic echocardiography. Postanesthesia hypotension was defined as mean arterial blood pressure of <60 mmHg or a decrease of >30% in the mean arterial pressure after sedation., Results: Minimum and maximum IVC diameters were significantly lower (P = 0.005 and P < 0.001, respectively) and IVC-CI was significantly higher (P < 0.001) in patients who developed hypotension. Similarly, right ventricular end-diastolic area (RV-EDA), right ventricular end-systolic area (RV-ESA), right ventricular end-diastolic volume (RV-EDV), right ventricular end-systolic volume (RVESV), and left ventricular end-systolic volume (LV-ESV) values were significantly lower in patients with hypotension (P < 0.05). Logistic regression analysis showed that dIVC min and RV-ESA were independent predictors of hypotension., Conclusion: IVC diameters and RV-ESA, RV-EDA, RV-ESV, and RV-EDV are good indicators of preoperative volume status and can be used to predict the patients at risk of developing hypotension., Competing Interests: none declared, (This work is licensed under a Creative Commons Attribution 4.0 International License.)

Background/Aim: Optic nerve sheath diameter (ONSD) measurement is one of the non-invasive techniques used for intracranial pressure (ICP) measurement. ICP changes have been evaluated based on ONSD measurements during many laparoscopic surgeries. However, such analyses in the obese patient populations are limited. This study aimed at investigating the effects of pneumoperitoneum and reverse Trendelenburg and head-up position on ICP based on ONSD measurements in obese patients undergoing laparoscopic cholecystectomy. Methods: This observational study included 60 female patients who were scheduled for laparoscopic cholecystectomy. Obese patients with a body mass index (BMI) of 30 and above were assigned to Group 1, while BMI < 30 patients were assigned to Group 2. The first ONSD measurement was performed just before insufflation (T1). The second measurement was taken 5 min after insufflation (T2), the third measurement 5 min after placing patients in the reverse Trendelenburg and head-up position (T3), and the last measurement 5 min after the deflation while the reverse Trendelenburg and head-up position was maintained (T4). Results: ONSD measurements at the T2 and T3 time points in Group 1 patients were higher than in Group 2 patients (P = 0.012 versus P = 0.020). Both measurement values were higher in obese patients. In Group 1 patients, T2 and T3 measurements were significantly higher than T1 and T4 measurements (T2 > T1; P < 0.001, T2 > T4; P < 0.001, T3 > T1; P < 0.001, and T3 > T4; P < 0.001). No significant difference between T2 and T3 and between T1 and T4 measurements were found. In Group 2 patients, T2 measurements were significantly higher than the T1, T3, and T4 measurements, while T3 measurements were significantly higher than T1 and T4 measurements (T2 > T1; P < 0.001, T2 > T3; P = 0.022, T2 > T4; P < 0.001, T3 > T1; P < 0.001, and T3 > T4; P = 0.048). No significant difference between T1 and T4 measurements was noted. Conclusion: Laparoscopic cholecystectomy does not cause an increase in ICP of obese patients with limited pneumoperitoneum pressure, reverse Trendelenburg and head-up position, and controlled anesthesia.

Introduction: In this study we aimed to compare the recovery characteristics of propofol/remifentanil and sevofluran/remifentanil anesthesia in 100 geriatric patients undergo-ing urological procedures. Materials and Method: The patients were randomized to receive either propofol-remifen-tanil (group P) or sevoflurane-remifentanil (Group S) anesthesia. Recovery characteristics, the time to post-anesthetic discharge scoring system (PADSS) score and Aldrete score of 9 point, Digit Symbol Substitution Test (DSST) and Trieger Dot Test (TDT)values were compared between two groups. Results: Extubation time was significantly shorter in group P than in group S (5.3+2.9 min vs 7.8+3.8 min, p=0.038). The times of first eye opening, response to verbal commands and ori-entation were similar in both groups. The time of Aldrete score of 9 points (grup P: 14.2+3.6 min, group S: 16.3+4.5 min) and PADSS of 9 points (group P: 19.3+5.7 min, group S: 22.1+4.2 min) were also similar (p>0.05). Time to return to the normal value of DSST was significantly shorter in Group P compared with Group S, and TDT was similar in both groups (p>0.05). No sig-nificant differences were observed in the incidence of postoperative complications and VAS score (p>0.05). Conclusion: Both propofol-remifentanil and sevoflurane-remifentanil appears to be an ade-quate anesthesia in geriatric patients. [ABSTRACT FROM AUTHOR]

The article offers information regarding a simple and economicalsimulation model created with easily obtained materials that provides real-time feedback for ultrasound guided regional anaesthesia. It adds that an effective implementation of ultrasound guided nerve block application depends on the accurate visualization of the needle tip. It discusses the materials required for the preparation of the model which are beef from a butcher, tendon and nerve tissue content.

Abstract: Study Objectives: To compare the postoperative analgesic efficacy and duration of analgesia after caudal levobupivacaine 0.20% with and without the addition of sufentanil 0.5 μg kg−1. Design: Prospective, randomized study. Setting: University teaching hospital. Patients: 40 ASA physical status I pediatric patients, aged one to 7 years, who were scheduled for elective minor subumbilical surgery. Interventions: Patients were divided into two groups to receive either a single caudal injection of one mL kg−1 levobupivacaine 0.20% (Group L) or levobupivacaine 0.20% plus sufentanil 0.5 μg kg−1 (Group LS). Measurements: Analgesia (Children and Infants Postoperative Pain Scale score), motor block (Motor Blockade Scoring), and side effects were assessed at predetermined time points during the first 24 postoperative hours. Main Results: The Children and Infants Postoperative Pain Scale scoring at the first hour was significantly lower in Group LS than in Group L. No significant differences were found between the two groups for pain scores at two, three, 4, 5, 6, 9, 12, and 24 hours. Degree of motor block was comparable between the two groups. Conclusion: The effect of adding sufentanil to caudal levobupivacaine on postoperative pain scores is brief after elective minor subumbilical surgery in children. [Copyright &y& Elsevier]
