Objective The Pain Sensitivity Questionnaire (PSQ) is a clinically beneficial instrument that has been proven to be correlated with various experimental pain sensitivity assessments in healthy people and in patients with chronic pain. In this study, we aimed to translate the PSQ into Turkish (PSQ-T) and validate it for the measurement of pain sensitivity among Turkish people. Methods Seventy-three patients with chronic back pain who were planning to undergo an interventional procedure completed the Brief Pain Inventory-Short Form (BPI-SF), Beck Depression Inventory (BDI), Beck Anxiety Inventory, Pain Catastrophizing Scale, and PSQ prior to their procedure. Subcutaneous infiltration of lidocaine was used as a standardized experimental pain stimulus. Pain was evaluated using a visual analog scale (VAS 1: infiltration in the hand, and VAS 2: infiltration in the procedure area) Results Scores on the PSQ-T were significantly correlated with those on the BPI-SF. A significant positive relationship was observed between VAS 1 and VAS 2 values and the PSQ-T score, BPI pain score, and BPI interference score. Conclusions The PSQ-T can be used as a valid and reliable tool for the assessment of pain sensitivity in the Turkish population.

Introduction The present study investigates how preoperative anxiety and pain sensitivity affect the consumption of anesthetics, time elapsed until the desired sedation level is achieved, preoperative hemodynamics, postoperative recovery time, and postoperative pain. Methods The present study includes 80 ASA 1–2 patients aged between 20 and 65 who were scheduled for endoscopic ultrasonography (EUS) under sedation. Patients were instructed to fill out the Spielberger State-Trait Anxiety Inventory (STAI) and Pain Sensitivity Questionnaire (PSQ) before the procedure. For sedation, 0.03 mg kg−1 intravenous midazolam, 1 mg kg−1 lidocaine, 1 µ kg−1 fentanyl, and then a bolus dose of 1 mg kg−1 propofol were infused over a period of 60 s. The time elapsed until the bispectral index (BIS) value reached 75 was recorded. For anesthesia maintenance, 2 mg kg−1 h−1 propofol infusion was administered. In the case of sedation failure, an additional dose of 0.1 mg kg−1 propofol (IV) was administered to ensure sedation depth with a BIS level of 65–75, and the propofol infusion was halted once the BIS value dropped below 65. Results STAI-S and STAI-T scores were significantly positively correlated with PSQ minor pain and PSQ total scores. The time elapsed until reaching a BIS level of 75, propofol infusion dose used during sedation, and the need for additional doses of propofol, heart rate (HR), and duration of post-anesthesia care unit stay were significantly positively correlated with both preoperative anxiety and preoperative pain sensitivity. In terms of postoperative pain, the visual analog scale (VAS) at 1 h was more highly correlated with STAI-S and STAI-T than with PSQ. The VAS 2 h was only correlated with STAI-S and STAI-T. Conclusion The significant linear correlation between preoperative anxiety and pain sensitivity and anesthesia need can facilitate better preoperative management by predicting individual anesthetic consumption. Trial Registration The study was registered with the number NCT03114735 on ClinicalTrials.gov.

Background: This study aimed to compare the changes induced by VCV and PCV modes in hemodynamics, respiration (airway pressures, gas exchange parameters) and metabolism (acid-base balance) in patients undergoing laparoscopic cholecystectomy. Methods: Patients were divided into two randomised groups as volume-controlled ventilation (VCV) group (VC) and pressure-controlled ventilation (PCV) group (PC). The following parameters were recorded at 3 different time points: T1: in supine position 10 minutes after induction of anaesthesia, T2: 15 minutes after CO 2 insufflation in inverted Trendelenburg position (head 30 degrees up), T3: 10 minutes after CO 2 desufflation. HR, SpO 2 , SAP (systolic arterial pressure), DAP (diastolic arterial pressure), MAP (mean arterial pressure), PetCO 2 (end-tidal carbon dioxide pressure), P peak , P plateau , P mean , Vt (tidal volume) and compliance with the available data, the cases in both groups Vd, Vd/Vt ratios and P(A-a)O 2 were calculated. Arterial blood gas parameters (pH, PaO 2 , PaCO 2 , SaO 2 , P(a-et)CO 2 ) values were recorded. Results: It was found that P peak and P plateau values were significantly higher in the VC group (p
