             Inclusion criteria

Peripheral vascular disease

After obtaining approval from Ethics committee. Informed and Written consent will be obtained from all patients .All patients will be instructed to fast  for  8 hours for solid diet prior to surgery. All patients will be pre medicated with Tablet Metaclopromide 10 mg  and Tab. Ranitidine 150 mg orally on the night before surgery and morning of surgery. Patients pre operative vitals will be recorded ( HR, BP, MAP, SPO2 and perfusion index ). An intravenous (IV) line will be established with an 18 G IV catheter in the dorsum of hand or wrist vein. All patients will be coloaded with Lactated ringer’s(RL) solution of approximately 500 ml. Standard monitoring with electrocardiography, non invasive blood pressure, pulse oximetry with perfusion index will be performed as per ASA guidelines .Baseline BP, MAP, HR, SPO2, PERFUSION INDEX  will be monitored and noted. Pulse oximeter will be put on the left hand and right and left second toes of parturients in supine position for continuous monitoring of toe and hand perfusion index until the fetus is delivered .The perfusion index of upper limb and right and left toe will be noted 5mins before spinal anasthesia in supine position. Under sterile aseptic precautions all patients will receive subarachanoid block at L3-L4 or L4-L5, level with patients in sitting position using 25 or 26 G Quincke needle. After cerebrospinal fluid is detected Inj 0.5% Bupivacaine(Hyperbaric)2ml with buprenorphine 0.2ml is administered.By use of a cold swab level of sensory block will be checked 5 min after spinal injection before starting surgery. Oxygen will be attached by use of face mask at 4 L/min to parturient after returned to supine position. After spinal anaesthesia, Heart rate (HR), Systolic blood pressure (SBP), Diastolic blood pressure (DBP), Mean arterial pressure (MAP), perfusion index (PI), saturation (SpO2) & respiratory rate(RR) will be recorded at 3 min intervals till the delivery of baby.The perfusion index of left hand and right and left toe will be noted 5mins after spinal anesthesia in supine position. Decrease in Systolic blood pressure less than 20% from the baseline SBP will be characterized as hypotension .Hypotension will be treated with IV fluid (Ringer lactate/normal saline),if required vasopressors (Ephedrine, Phenylephrine, Noradrenaline. Any adverse effects like nausea, vomiting ,headache, bradycardia will be treated accordingly.
