A study on patients receiving medication for elevated blood pressure (Calcium channel blocker medications) using a monitor in the operating theatre (Surgical Plethysmographic Index) as a tool to determine the level of pain after operations.

An observational study to evaluate the utility of surgical plethysmographic index as a tool to predict postoperative pain in patients receiving oral calcium channel blocker therapy.

Eligibility

Inclusion criteria

Inclusion criteria: 1) Patients undergoing procedures requiring general anaesthesia 2) Patient must be on calcium channel blockers therapy 3) American Society of Anesthesiology (ASA) 2 patients 4) Patients in age range 19-60 years

Exclusion criteria

Exclusion criteria: 1) Patients on pacemaker 2) Patients who are diagnosed with any form of arrhythmia 3) Patients with compromised kidney function (GFR less than 60 ml/min/1.73m2) 4) Patients posted in an operating theatre not equipped with SPI monitor 5) Patients who are on tourniquet as tourniquet pain may affect SPI value

Design outcomes

Primary

MeasureTime frame
To determine whether the value of SPI obtained 10 minutes before expected completion of surgery can be used as a reliable tool to predict postoperative pain in patients receiving oral calcium channel blocker therapy for hypertension.Timepoint: In the last ten minutes of the procedure, SPI values for each minute will be noted. For example if the procedure is from 12pm-1pm, the SPI values from 12:50-1pm will be noted. Ten values will be noted for each minute.

Secondary

MeasureTime frame
To determine if the SPI can be used as a tool to predict awakening of the patient from anaesthesia.Timepoint: In the last ten minutes of procedure, SPI values will be noted.For example if the procedure is from 12pm-1pm, For each minute we shall note down an SPI value starting from 12:50-1pm for a total of ten values.
