Sample of the study-The sample of the study was a stratified random sample

Sample size-The sample size for this study was based on Cohen`s formula for multiple regression (29).(N=Lambada/f 2),in this case the effect size of 0.25 was used. An alpha of 0.05 is considered a convention for significance. Lambada is determined to be 7.8,N=7.8/0.25 = 31.2,there are one independent variable and three dependent variable. In this study sample 93 was recommended.

Functional Measures

(1) Immediate post-operative cares following cardiac surgery for Cincinnati Pediatric Hospital (30)

-Suitable positioning on the bed (a semi-to high Fowler's position)

2 - Monitoring for Catheters:

1 - Oxygen therapy.

2 - Central Venous Pressure.

3 - Open thoracic drains (place thoracic drainage bottle in a suitable recipient).

4 - Check position of nasogastric tube

5 - Investigate the position of the tracheal cannula and its correct fixation

-Set respirator parameters, connect the patient to the respirator

-Physical evaluation: skin and mucous color, capillary refill, level of hydration

-Routine tests are requested sodium, potassium, calcium, glycemia, hematocrit, and hemoglobin three times a day for the first 2 days and once a day after extubation and hemodynamic stabilization, uric acid, coagulation tests and creatinine are requested daily.

3 - Basic Monitoring:

1 - Heart beat for detecting cardiac arrhythmia.

2 - Arterial pressure for measurement of diastolic and systolic pressures continuous infusion of heparin with saline (1 U/ml).
