About

Prospective, randomized control trial To determine if oral caffeine decreases the frequency of opioid demand in children with adolescent idiopathic scoliosis after their spinal fusion surgery To compare pain scale ratings, number of requests for diazepam, average heart rate, average blood pressure, sex, age, ethnicity, post-op day of discharge, operative time, estimated intraoperative blood loss, remittance post-surgery, length of hospital stay, and segments fused during spinal fusion surgery.

Full description

Because these receptors are so important for modifying pain and inflammation, caffeine has been added as an adjuvant to common analgesics, such as paracetamol, ibuprofen, and aspirin in the belief that it will enhance their analgesic efficacy. Most studies used paracetamol or ibuprofen with 100 mg to 130 mg caffeine, and the most common pain conditions studied were postoperative dental pain, postpartum pain, and headache. There was a small but statistically significant benefit with caffeine used at doses of 100 mg or more, which was not dependent on the pain condition or type of analgesic. Additionally, trials have shown superior efficacy of adding caffeine to ibuprofen instead of administering ibuprofen alone for treating acute pain, reflecting that caffeine is an effective analgesic adjuvant. The addition of caffeine (≥ 100 mg) to a standard dose of commonly used analgesics provides a small but important increase in the proportion of participants who experience a good level of pain relief. Finally, the beneficial effects of caffeine on aerobic activity and resistance training performance are well documented. Studies have shown that caffeine ingestion resulted in significantly lower levels of soreness compared with placebo (p ≤ 0.05). A further beneficial effect of sustained caffeine ingestion in the days after the exercise bout is an attenuation of delayed onset muscle soreness. Orthopaedic surgery also causes muscle injury, and patients might benefit from caffeine's effect on lowering muscle soreness. Acute caffeine administration also has been shown to demonstrate increases in alertness, contentment, motivation to work, talkativeness, and energy. It also decreases muscle twitches. All of these effects would be beneficial in the post-operative period, especially for Adolescence Idiopathic Scoliosis (AIS) patients undergoing spinal fusion surgery in the orthopaedic department at Children's Mercy Hospital.

81 participants in 2 patient groups, including a placebo group

Caffeine arm
Active Comparator group
Description:
Experimental Group: patient group (n = 34) receiving a 100 mg dose of caffeine (1/2 of a 200mg tablet to be taken whole or crushed), taken twice daily. This will be an adjuvant to their standard pain control.
Treatment:
Drug: Caffeine Tablet
Placebo arm
Placebo Comparator group
Description:
Control group: patient group (n = 34) receiving placebo compounded to look similar to the caffeine treatment, taken twice daily. This will be an adjuvant to their standard pain control.
Treatment:
Drug: Caffeine Tablet
Drug: Placebo
