Imran Technique for Spinal Anesthesia and Lumbar Puncture

This quasi-experimental prospective clinical trial was conducted to compare the conventional sitting position with the Imran Technique, a novel ergonomic patient-positioning method, for spinal anesthesia and lumbar puncture. A total of 200 adult participants requiring spinal anesthesia for surgical procedures or diagnostic lumbar puncture were allocated into two groups. The study aimed to evaluate procedural success, procedural efficiency, patient comfort, operator ergonomics, and procedure-related complications associated with the two positioning techniques.

Effectiveness of Detachment of the Breathing Circuit on the Rate of DLT Malposition After Postural Change

The goal of this clinical trial is to assess the incidence of double-lumen endobronchial tube displacement in patients undergoing thoracic surgery with a change in position, compared with double-lumen endobronchial tube malposition in chest surgery patients with a fixed breathing circuit. The study is to investigate: whether detaching the breathing circuit in patients undergoing thoracic surgery would reduce the rate of double-lumen endobronchial tube malposition, the incidence of postoperative pulmonary complications, and improve patient outcomes. Participants will be randomly divided into a disconnected breathing circuit group and a breathing circuit connected group and after entering the operating room, the intravenous access will be opened, and blood pressure, heart rate, electrocardiogram, oxygen saturation, arterial pressure, and end-expiratory carbon dioxide will be monitored. Anesthesia induction will be performed by an anesthesiologist, and then the double-lumen endobronchial tube will be inserted under laryngoscopic guidance. Will the catheter be delivered to the expected depth, the double-lumen endobronchial tube will be connected to the anesthesia machine for mechanical ventilation. Researchers will compare the malposition rate of the double-lumen endobronchial tube when the patient transitions from the supine to lateral decubitus position, the effect of single-lung ventilation, oxygen saturation at 5 and 10 minutes after single-lung ventilation, and postoperative recovery time.
