Analgo-Sedative Effects Of Oral, Or Nebulized Ketamine In Pre-schoolers Undergoing Elective Surgery.

Postoperative Analgesia Clinical Trial

Official title:
Analgo-Sedative Effects Of Oral, Or Nebulized Ketamine In Pre-schoolers Undergoing Elective Surgery: A-Comparative Randomized Double Blind Study

Clinical Trial Summary

the primary objective of this study is to investigate the sedative, and analgesic effects of oral, or nebulized ketamine as premedication drugs, and providing postoperative analgesia for the preschoolers and decrease their need for systemic analgesia.The secondary objective is to compare each sedation technique after oral, or nebulized ketamine for safety ,and procedural outcomes.

Clinical Trial Description

Preoperative communication, premedication interventions, and being accompanied by parents are useful methods in decreasing preoperative separation anxiety , postoperative psychological trauma, and ensuring smooth induction for preschoolers undergoing elective surgery.

Procedural sedation, and analgesia was defined by O'Donnell as a drug induced state of decreasing awareness, pain, and memory that allowing patient continue his ,or her own protective reflexes, and moving purposefully( O' Donnell etal, 2003).

Ketamine is an anesthetic drug having sedative, and analgesic properties with different routes of administration in children (IV, intramuscular, subcutaneous, oral, rectal, sublingual, intranasal, and nebulized) .

Ketamine produces its analgesic properties in acut pain management from reversible antagonizing the N-methyl-D-aspartate (NMDA)receptors , reducing levels of many proinflammatory mediators in the acute phase, and acting on other non-NMDA pathways that playing important roles in pain, and mood regulation, like its effect on µ-opioid receptors, nicotinic, muscarinic cholinergic, ɣ-aminobutyric acid receptors, activation of high -affinity D2 dopamine receptors, and L-type voltage-gated calcium channels.

The oral route is the most popular than other routes ,as it's safe, efficient, acceptable, and familiar for pediatric patients..

Oral ketamine often requires higher, and frequent doses as it's bioavailability is lower (17-24%) compared to IV (100%),Intramuscular (93%), sublingual/transbuccal(30%), intranasal(25-50%),and inhaler (70%) due to extensive first pass metabolism in liver, and intestine.

Ketamine inhalation is safe, rapid absorption, and affordable route of administration. ;
