Brief Summary:
The purpose of the study is to compare dexmedetomidine and ketofol to find a suitable alternative for moderate sedation in out-patient diagnostic trans-esophageal echocardiography.

Condition or disease Intervention/treatment Phase
Heart Valve Disease Heart Septal Defects, Atrial Drug: Dexmedetomidine Drug: Ketofol(ketamine+propofol) Phase 4

Detailed Description:

Sample size was estimated based on previous studies with sedation in equally invasive procedures that in 2 groups difference in time to achieve Ramsay sedation scale was 0.8min.(In group dexmedetomidine 12.4 & group ketofol 13.2 with S.D of 0.8). The sample size came out to be 22 subjects per group at a power of 90 % & confidence interval of 95 %. For possible dropouts, it was decided to include 10% extra subjects so finally it was decided to include 25 subjects per group. (Total sample size 50 subjects)

Normality of quantitative data will be checked by measures of Kolmogorov Smirnov tests of normality. If data is normally distributed Student t-test will be applied for comparison of 2 groups. Mann-Whitney U-test will be used for statistical analysis of skewed continuous variables or ordered categorical data. Proportions will be compared using Chi square or Fisher's exact test whichever is applicable. Wilcoxon Signed rank test will be used for skewed data or for scores (time related variables). . For comparison (time related variables) of Hemodynamics Repeated Measure ANOVA will be applied. All statistical tests will be two-sided and will be performed at a significance level of α=0.05. Analysis will be conducted using SPSS for Windows

Arm Intervention/treatment
Active Comparator: Group D
Dexmedetomidine- drug used for moderate sedation prepared as 200 mic in 20 ml syringe.with intravenous loading dose at 1ml/kg/hour till required sedation is achieved and maintenance infusion of 0.05mg/kg/hour till completion of transesophageal echocardiography
Drug: Dexmedetomidine
drug for moderate sedation in trans-esophageal echocardiography

Active Comparator: Group KF
Ketamine+Propofol -drugs used for sedation-as ratio 1:3with 19ml of 1% propofol + 1.3ml ketamine(50mg/ml) as loading intravenous infusion dose at 1ml/kg/hour till required sedation is achieved and maintenance infusion of 0.05mg/kg/hour till completion of transesophageal echocardiography
Drug: Ketofol(ketamine+propofol)
drug for moderate sedation in trans-esophageal echocardiography




Primary Outcome Measures :
  1. Time taken to achieve adequacy of sedation before probe insertion. [ Time Frame: maximum of 10 minutes ]
    Adequacy of sedation to be measured using Ramsay Sedation Scale (>=3 considered adequate for probe insertion)


Secondary Outcome Measures :
  1. Recovery time [ Time Frame: Upto 30 minutes ]
    Time to achieve modified aldrete score >9

  2. Heart rate during procedure [ Time Frame: every 5 minutes till end of procedure ]
    Heart rate in beats/min, , facial pain score as 0-10

  3. mean arterial pressure during procedure [ Time Frame: every 5 minutes till end of procedure ]
    mean arterial pressure in mmHg,

  4. Oxygen saturation during procedure [ Time Frame: every 5 minutes till end of procedure ]
    oxygen saturation in %

  5. End tidal carbondioxide during procedure [ Time Frame: every 5 minutes till end of procedure ]
    End tidal carbon dioxide in mm Hg
