Phase 2
Recruiting
Conditions
Post Spinal Anesthesia Shivering
Interventions
Drug: Normal Saline 10 mL Injection
Registration Number
NCT06031090
Lead Sponsor

Brief Summary

Prevention of post spinal anesthesia shivering during cesarean section with its associated discomfort, distress, aggravation of pain, increased metabolic demands, and increased oxygen consumption

Detailed Description

Shivering is one of the most important periperative complications seen in clinical practice. Several mechanisms have been postulated for its pathogenesis. Anesthetic-induced inhibition of thermoregulation resulting in hypothermia is an important cause of post anesthesia shivering, uncontrolled spinal reflexes, and cutaneous vasodilation are the other suggested mechanisms involved in the pathogenesis of shivering. Opioid receptors, α2 receptors, and serotonergic receptors also are involved of shivering.

Various drugs were studied for their potential role in prevention of peri-operative shivering such as tramadol, dexmedetomidine, ondansetron, ketamine, and pethidine.

We decided to perform a well-designed study to compare clonidine and granisetron which has been recently introduced as drugs for prevention and control of shivering after spinal anesthesia.

Primary Outcome Measures
NameTimeMethod
Incidence of ShiveringProcedure (through out the period of spinal anesthesia)

• Shivering will be graded according to Tsai and Chu scale (10): 0 = no shivering, 1 = piloerection or peripheral vasoconstriction but no visible shivering, 2 = muscular activity in only one muscle group, 3 = muscular activity in more than one muscle group but not generalized shivering, 4 =shivering involving the whole body

Secondary Outcome Measures
NameTimeMethod
core body temperatureProcedure (preoperative as base and through out the period of spinal anesthesia)

Core body temperature was detected by measuring tympanic membrane temperature using digital infrared ear thermometer (thermoscan KFT-10; Grnzia, genova, Italy).

Maternal Heart rateProcedure (preoperative as base and through out the period of spinal anesthesia)

beats/minute

baby APGAR score1 minutes and 5 minutes post natal
maternal blood presureProcedure (preoperative as base and through out the period of spinal anesthesia)
