  Purpose

OBJECTIVE: To determine the efficacy of ketamine-propofol anesthesia in a mixture 1:2 (1 mg of ketamine per 2 mg of propofol) for short minimally invasive surgical procedures.

METHODS: The investigators performed a prospective study through randomization of 77 patients undergoing short surgical procedures in two study groups: one received a mixture of ketamine-propofol in a 1:1 ratio, and the other received a 1:2 mixture. Data were stored in an Excel spreadsheet and analyzed using the statistical program Epi-Info (TM) 3.5.3. The investigators performed the comparison of qualitative and quantitative variables.

KEY WORDS: ketamine, propofol, anesthesia.

Primary Outcome Measures:
  • EFFICACY OF KETAMINE-PROPOFOL FOR SHORT SURGICAL PROCEDURES [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    Sedation / analgesia was considered successful if the procedure was completed without the need for other anesthetic drugs are different from the protocol, and yes no adverse effects to oblige the completion of the procedure. Apnea was defined as cessation of breathing for at least 20 seconds. Hypotension was defined as 20% decrease in mean arterial pressure. Bradycardia was defined as a pulse of less than two standard deviations below normal values defined by the American Heart Association (AHA_ for its acronym in Ingles_). Hypoxia was defined by an oxygen saturation of less than 90%.

Arms Assigned Interventions
Active Comparator: Ketofol 1:1
1. Anesthesia-sedation KETOFOL 1-1: Two milligrams per kilogram of ketamine plus two milligrams per kilogram of propofol in a solution 1:1 (one milligram of ketamine per one milligram of propofol) was given to those patients randomly asigned to this group, who were scheduled for any short surgical procedures previously defined in the inclusion criteria.
Drug: Ketamina-Propofol Combination

After randomization to the study group, the patients were given:

Procedures < 10 minutes

  1. Ketamine-Propofol Combination KETOFOL 1:1

    • Propofol: 0.2 cc/kg (10 mg/cc = 2 mg/kg)
    • Ketamine: cc/kg 0.04 (50 mg/cc = 2 mg/kg)
    • Simple 1% lidocaine: 0,1 cc/kg (10 mg/cc = 1 mg/kg)
  2. Ketamine-Propofol Combination KETOFOL 1:2

    • Propofol: 0.2 cc/kg (10 mg/cc = 2 mg/kg)
