Ultrasound guidance in anaesthesia is becoming an important tool in Anaesthesiologists. Sonography helps in addressing a variety of consequences such as patient safety, economic burden, duration of the procedure and success rates associated with invasive anaesthesia procedures. Consent from 50 patients were obtained in their own understandable language. After thorough pre-anaesthetic evaluation and overnight fasting, patients shifted to operation theatre and following monitors are connected. (Pulse oximeter, electrocardiogram, capnograph and non-invasive Blood pressure) Patients were randomly allocated into 2 groups (Group D and Group S) as per computer generated randomization table. The average diastolic blood pressure in both the groups was maintained from the baseline till 24 hours of observation. There was neither clinical nor statistical significant variation found. We did not find any clinical variations in the heart rate, SBP, DBP, MAP, RR of the patients preoperatively, intra and also postoperative period. All the recruited patients had maintained oxygen saturation >95% throughout the surgery.
