Children scheduled for the various surgical procedures and satisfying the inclusion and exclusion criteria will be included in this study. Each child’s relevant history will be taken. Through examination will be done. Laboratory parameters and other investigations will be noted.

Each child will be assigned ASA PS score and pediatric version of SHAPE score. 

The same child will be again evaluated as per SHAPE’s scoring system.

1.   ASA score of each system will be given as per SIS (SHAPE’s Individual Systems score). 

2.   Surgical risk / invasiveness will be scored.

3.   Physical features affecting mask ventilation will be scored.

4.   Intubation difficulty predicting features will be scored.

5.   Any special risk related to anesthesia will be graded.

6.   Final ‘ASA PS’ score will be given as single digit with extra suffice ‘E’ for emergency surgery. Final ‘SHAPE^’ score will be given in the range 1,1,0,0 to 5,5,5,5 and additional risk indicator if any.

Both completed evaluation forms will be given to anesthetist in charge of that case. The intraoperative and postoperative anaesthesia care plan including premedication, induction, ion etc. will be according to attending anesthesiologist’s discretion. After the surgery, his/her opinion about both scoring systems will be taken in the form of questionnaire.

Intra-operative and post-operative complications will be followed up till patient is discharged from intensive care unit.

Descriptive statistic about height, weight sex will be noted. Intra operative and post-operative complications and requirement of escalation of care will be noted.

Relation between categorical and dichotomous variable will be analyzed by univariate and multivariate logistic regression models using SPSS. Odds ratio and 95% confidence intervals will also be calculated during bivariate logistic regression analysis. Comparison between area under curve (AUC) of two receivers operating characteristic (ROC) curves will be carried out.
