Brief summary

The purpose of this study is to determine if the antisialagogues (anti-salivary agents), Atropine and Glycopyrrolate, are effective in reducing hypersalivation when sedating patients with Ketamine for procedural sedation in the emergency department or abscess clinic. The investigators will measure salivary flow rate by collecting oral secretions by oral suctioning over a 30 minute time period starting with the administration of Ketamine. The investigators hypothesize that patients who receive either atropine or glycopyrrolate will have fewer oral secretions than patients who receive placebo.

Detailed description

Ketamine is a common sedation agent used in the pediatric emergency department for a variety of procedures, used in clinical practice since 1970. One potential side effect of Ketamine is hypersalivation, potentially leading to laryngospasms. To prevent hypersalivation (and reduce the potential for laryngospasms), an anti-salivary agent, such as Atropine, is commonly given in combination with Ketamine. Recently, however, the necessity of this practice has been brought into question. The consideration of using a different drug, glycopyrrolate, has been debated. The purpose of this study is to compare the effectiveness of each medication in addition to the placebo control. Patients enrolled into this study must present to the emergency department or abscess clinic with the need to receive Ketamine as part of a sedation procedure (as determined by the treating physician). This study will randomize enrolled patients to receive double-blinded Atropine, Glycopyrrolate or placebo given 30 minutes prior to Ketamine. After Ketamine is administered, a trained medical person will suction the patient's mouth every 5 minutes for a total of 30 minutes, collecting all oral secretions. Total saliva production will be measured and salivary flow rates will be calculated and compared between each assigned group. Adverse events and complications will be monitored throughout the patient's stay in the emergency department or abscess clinic.

Interventions

DRUGAtropine (0.01mg/kg)

Atropine will be given at 0.01mg/kg with a minimum dosage of 0.1mg and a maximum dosage of 0.4mg. This medication will be given once by IV 30 minutes before the administration of Ketamine.

DRUGGlycopyrrolate (0.01mg/kg)

Glycopyrrolate will be given at 0.01mg/kg with no minimum dosage and a maximum dosage of 0.4mg. This medication will be given once by IV 30 minutes before the administration of Ketamine.

DRUGNormal saline 0.9%

Normal Saline of 0.9% will be given at a volume of 2mL. This medication will be given once by IV 30 minutes before the administration of Ketamine
