简要总结
A total of 76 patients undergoing elective surgery will be randomly allocated to two groups of
38 patients each using computer generated random number table and the allotted number will
be secured in a coded opaque sealed envelope. The patients will be allocated to one of the
following two groups:
Group R (n=38): Patients will be given 3ml of 0.75% Hyperbaric Ropivacaine intrathecally
Group L (n=38): Patients will be given 3ml of 0.5% Hyperbaric Levobupivacaine intrathecally
Procedure on day of surgery:
Patient will be shifted to the operation room. Monitoring of heart rate, systolic blood
pressure, diastolic blood pressure, mean arterial blood pressure, continuous
electrocardiogram, respiratory rate, and oxygen saturation (Spo2). Baseline values will be
recorded.
After subarachnoid block has been given, assessment of sensory block will be done using sterile
pin prick method and motor blockade will be done using Modified Bromage scale. Assessment will
be done every minute for the first 10 minutes and then every 10 minutes during surgery and every
15 minutes postoperatively. Onset of both motor and sensory blockade will be assessed and
recorded. The highest dermatomal level of sensory blockade and recovery time of both sensory and
motor blockade will be recorded. Recovery time for the sensory blockade will be defined as the two
dermatome regression of anaesthesia from the maximal level.
Patients will receive rescue analgesia accordingly. The time of first
request for analgesia postoperatively will be recorded as total duration of spinal analgesia.
Patient will be monitored continuously intra and post operatively and observations will be recorded
in the prescribed proforma.
