measurement of bromage scale every 15 minutes from spinal anesthesia to the end of the surgery

measurement of time required for bromage scale to regress from 3 to 0

Neonatal Apgar score will be recorded at 1 minute after delivery. The Apgar score is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two, then summing up the five values thus obtained. The resulting Apgar score ranges from zero to 10. Scores 7 and above are generally normal; 4 to 6, fairly low; and 3 and below are generally regarded as critically low and cause for immediate resuscitative efforts

Neonatal Apgar score will be recorded at 5 minutes after delivery. The Apgar score is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two, then summing up the five values thus obtained. The resulting Apgar score ranges from zero to 10. Scores 7 and above are generally normal; 4 to 6, fairly low; and 3 and below are generally regarded as critically low and cause for immediate resuscitative efforts
