Clinical Trial Summary

Ketamine and Midazolam are well known sedative drugs that can be given through different routes such as intravenous, intramuscular, oral, rectal and intranasal route. Anesthetic staff usually prefer intravenous route but sometimes inserting venous access is difficult in uncooperative mentally disabled children. Intranasal ketamine+Midazolam can be a needless effective alternative in these vulnerable patients

Description:

Sedation and analgesia decreases the need for general anesthesia outside the operating room. Intravenous route is the standard way of sedation, but its use can be limited in uncooperative mentally disabled children. Active Physical restraint of children causes emotional trauma for both parents and children particularly in these patients. Oral sedation has multiple disadvantages as delayed onset of action, better taste, the need of different types of syrup or honey according to the preference of the patient, children may refuse to take oral drugs or even spit it and it also causes postoperative nausea and vomiting. In contrast, intramuscular sedation is an easy effective way of administration and it is preferred due to its rapid onset of action and higher predictability of the duration, however, fear of the pain of injections is considered a disadvantage in this vulnerable pediatric patients. nasal route is an important alternative route because it is a painless and needless approach with rapid drug absorption from nasal mucosa reaching the cerebrospinal fluid and bypassing the first pass metabolism in the liver. Intranasal midazolam for sedation of children was first described by Wilton et al .Recently studies proved the use of nasal ketamine spray for treatment of resistant depression in adults. Ketamine as a premedication in children has been also successfully given through the nasal route. In Ain shams University hospitals we give either oral Midazolam or intramuscular Ketamine followed by sevoflurane or propofol for pediatric procedural sedation. Nasal Midazolam or Ketamine has not been tried despite being a feasible choice with many possible advantages. Combination of ketamine and midazolam causes deeper sedation and less dysphoric reaction of ketamine so in this study, we evaluate the efficacy and safety of administration of this combination through intranasal route for procedural sedation in children with mental developmental delay outside the operating room.

After approval from our Ethical Committee, written informed consent from the parents will be taken. Forty children presented with autism,mongolism or cerebral palsy classified as American Society of Anesthesiologists (ASA) physical status I and II, aged between 4 and 12 years will be enrolled in our study, and computer-generated assignment will be used for randomization and to allocate patients to one of two equal study groups.

patients will fulfill the fasting hours if elective while the patients in ER will be asked to wait for six hours after last meal.

Patients will be divided into two groups Group IN:will receive intranasal ketamine 5 mg/kg and midazolam 0.2 mg/kg, and we will give intranasal sedatives by using mucosal atomisation device.

Group IM:will receive intramuscular ketamine 5 mg/kg, and midazolam 0.2 mg/kg Sedation levels after 10, 20, and 30 min will be evaluated by Pediatric Sedation State Scale (PSSS).

Drugs will be given 15- 20 minutes before procedure then Heart rate (HR), Oxygen saturation (Spo2), and mean arterial blood pressure (MBP) will be continuously monitored and recorded every 5 min after drug administration for 60 minutes .

Local anesthesia will be given in painful procedures. Intravenous ketamine 1 mg/kg will be given if needed due to prolongation of procedure or if required sedation level not reached through intranasal or intramuscular route.

respiratory events as airway obstruction and desaturation less than 92% will be treated by jaw thrust and oxygen supplementation, apnea or laryngeal spasm will be managed with endotracheal intubation. Wheezing will be recorded and properly managed with bronchodilators and steroids.

Emergency cart and drugs will be available for haemodynamic and respiratory instabilities.

After recovery of the patients, parents and doctors will rate their overall satisfaction by using simple image of 5 point Likert scale.

Primary outcome: effectiveness of sedation. Secondary outcome: onset, duration of sedation, adverse effect, parents and doctor satisfaction.

End point of the study: if our technique failed to sedate the patients general anesthesia will be given either intravenous ketamine 1mg/kg or inhalational sevoflurane to complete the procedure.

Type	Measure	Description	Time frame	Safety issue
Primary	change in sedation level after intranasal or intramuscular ketamine midazolam mixture administration.	sedation level measured by Pediatric Sedation State Scale (PSSS): State 5: Movement impedes procedure and requires forceful immobilization; State 4: Movement requires gentle immobilization for positioning; State 3: Facial expression of pain or anxiety; State 2: Quiet, not moving, no frown, no verbalization of complaint (ideal state); State 1: Deeply asleep with normal vital signs, but requires airway intervention or assistance (e.g., central or obstructive apnea); State 0: Deeply asleep with abnormal physiologic parameters that require acute intervention (e.g., O2 saturation <90%, hypotension, bradycardia); highest score is 0 and least score is 5	every 10 minutes through the study till one hour after administration
Secondary	parents satisfaction	image form of 5 point likert scale. 5-very satisfied 4-Satisfied 3-Neither satisfied nor dissatisfied 2-Dissatisfied; 1-Very dissatisfied least score is 1 and highest score is 5	two hours after administration
