- Hypotension after subarachnoid block in immediately lying down, lying down after one minute sitting position and lying down after two minutes sitting position groups. Parameters such as heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, oxygen saturation of blood will be measured.

简要总结
Subarachnoid block is the most commonly employed technique for infra umbilical surgeries. It is widely accepted due to its ease of administration, reliability and rapid onset.
However, hypotension is one of the most common and inevitable complication which occurs immediately after subarachnoid block owing to high intrathecal spread. Incidence of hypotension in normal population is 16 to 33 percent. Various preventive measures have been attempted to reduce incidence of hypotension namely delayed positioning technique, vasopressor addition, fluid preloading and co loading.
Delayed positioning technique in post subarachnoid block has shown to have better hemodynamic stability. Various studies have shown that patient who were positioned sitting post subarachnoid block for one minute, two minutes, three minutes and five minutes had less incidence of hypotension.
Allowing the patient to remain in sitting position for some time after subarachnoid block delays onset of action, decreased higher dermatomal spread and decreased incidence of hypotension.

结局指标
主要结局
Hypotension after subarachnoid block in immediately lying down, lying down after one minute sitting position and lying down after two minutes sitting position groups. Parameters such as heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, oxygen saturation of blood will be measured.
时间窗: Time in minutes, | At One minute for first ten minutes, every two minutes for next ten minutes, for every five minutes till the end of surgery.
次要结局
- To evaluate the highest level of sensory block in all three groups.(To determine the time taken to reach highest sensory block in all three groups.)
