简要总结
Radial Artery cannulation using conventional palpation vs USG guided Dynamic needle tip positioning (DNTP) method.
详细描述
Management protocol of patients
A day before surgery All the patients included in the study will be explained in detail about the purpose of the study, and the need, benefits, and risks of arterial cannulation and the purpose of the study.
Written informed consent will be obtained during the pre-anaesthetic checkup. Patients will be asked to remain nil per oral as per standard American Society of Anesthesiologists guidelines. Premedication will be advised as per institutional protocol.
Pre-anaesthetic room After shifting from the ward to the pre-anaesthetic room, an intravenous line will be secured with an 18 or 20 G cannula in the dominant hand and baseline heart rate, blood pressure and oxygen saturation will be recorded. The patient will then be shifted to the operation theatre.
Operation theatre After shifting to the operating table, a pulse oximeter, a non-invasive blood pressure monitor, and an electrocardiogram monitor will be attached.
