The Effects of Keeping the Patient in a Sitting Position for One Minute After Spinal Anesthesia

The aim of this study was to examine the effect of keeping the patient in a sitting position for 1 minute after spinal anaesthesia in elective caesarean operations, primarily on the formation of hypotension and secondarily on nausea-vomiting, the need for ephedrine and the block characteristics.

    Time frame: 1 hour after spinal block

    the time to first administration of ephedrine as minutes after spinal block

  3. amount of ephedrine

    Time frame: 1 hour after spinal block

    administrated total ephedrine dosage as mg during surgery

  4. surgeon and patient satisfaction

    Time frame: 24 hours after spinal block

    1= poor, 2=fair, 3= good, 4= very good
