Objective: To compare the ease of placement of arterial catheters using palpation versus ultrasound guidance under aseptic measures. Study Design: Quasi-experimental study. Place and Duration of Study: Combined Military Hospital, Rawalpindi Pakistan, from Feb to Aug 2022. Methodology: Patients of either gender, aged 18 to 90 years presenting to a paranesthesia clinic that required intra-arterial blood pressure monitoring were included in the study. After induction, under General Anaesthesia, arterial lines were placed following an aseptic technique using ultrasound or palpatory method; in Group-U (ultrasound) or Group-P (Palpation), respectively. Demographic variables of the patient along with hemodynamic readings and success rate at first or multiple attempts, along with the total time of cannulation, were recorded. Results: Out of the total 74 patients, 59(79.7%) patients belonged to ASA-1 Grade, and 15(20.3%) patients in ASA-2 Grade. The mean age of the patients was 48.3±16.3, while mean BMI was 25.42±2.8kg/m2. In Group-P, the first-pass success was achieved in 19(51.4%) patients as compared to 32(86.5%) in Group-U when ultrasound was used (p<0.05). Conclusion: The success rate in placing an arterial line using ultrasound was significantly greater than the conventional palpatory method. Therefore, ultrasound should be a preferred modality during intra-arterial line placement. [ABSTRACT FROM AUTHOR]

Objective: To compare the ease of intubation using glide scope video laryngoscope versus direct laryngoscopy for nasotracheal intubation. Study Design: Quasi experimental study. Place and Duration of Study: Combined Military Hospital, Rawalpindi Pakistan, Aug 2022 to Feb 2023. Methodology: Patients of either gender with age greater than 18 years with American Society of Anesthesiologists (ASA) Grade I or Grade II planned for elective dental or maxillofacial procedures requiring nasotracheal intubation were included. A total of 60 patients were included, with 30 patients in each group. Recorded variables were time to intubate, glottic grade, use of Magill forceps, first attempt success, failure to intubate and postoperative sore throat. Results: With 60 patients after randomised allocation, 30 were allocated to Group-DL (Direct laryngoscopy) and Group-VL(Video laryngoscopy). The success rate in the first attempt was 27(90%) in Group-DL vs 30 (100%) in Group-VL, and the number of patients who could not be intubated was 1(3.3%) vs 0(0%) in both groups. The glottic grade recorded by the operator under vision, time to intubation, use of Magill forceps and post-operative sore throat in both groups was significant with a p-value of <0.05. Conclusion: Glide scope video laryngoscopy provides a better view of the vocal cords with less time to intubation, greater chances of successful intubation, and fewer post-operative chances of sore throat than direct laryngoscopy.
