ABSTRACT:

BACKGROUND: Surgical prophylaxis is essential for all surgeries sutures insertion of devices etc. Rational use of these antibiotics can minimize the post-operative nosocomial infections. The selection of these antibiotics should clearly be different from regular usage including time of administration.

METHODOLOGY: All inpatients subjected for surgery is the surgery ward is included in the study. Patient details such as patient demographics (age, sex, diagnosis), nature of surgery, timing, antibiotics, type and class of antibiotic were noted. The study was conducted after obtaining informed consent from the patient,

RESULTS: There is more use of Gentamycin in patients subjected for surgery. Appropriateness has been evaluated in correction with ASHP guidelines for management of antimicrobials for surgical prophylaxis and almost 90% appropriateness is seen with the therapy.

CONCLUSION: Surgical prophylaxis is an essential part of surgery with this study, we can help is designing apart of surgical kit necessary antibiotic for prevention the related nosocomial infection.

 

KEYWORDS: Surgical Prophylaxis, Antibiotics, Nosocomial Infections.

 

 


INTRODUCTION:

Surgery is one of the most common site for the manifestation of infections.1 These infections are pretty serious as they tend to be a direct infection on the systemic circulation. Hence the prevention of infections plays a major role in the safety of patient’s hospital stay.2

 

Surgical prophylaxis is essential for all surgeries sutures insertion of devices etc. Rational use of these antibiotics can minimize the post-operative nosocomial infections.3 The selection of these antibiotics should clearly be different from regular usage including time of administration.

 

The selection of these antibiotics for surgical prophylaxis should be based completely on patient specific factor such as allergy status, tolerability, pathogen nature etc.4

 

It is important to select antibiotic that could be ideal and not be resistant to the pathogen.5 The usually preferred route of administration for surgical prophylaxis is intravenous bolus or intra venous infusion route.6 The timing of administration also plays a major role in the prophylaxis.7 Usually preferred is within 1hour before the insertion of needle.8 Rectal and oral route can be also be given but it is based on the patient’s state.

 

Sayer I al-azzam  et al conducted  the  study on  preoperative  antibiotic prophylaxis  and guideline  adherence in Jordan : a multi-center study in Jordanian  hospitals. Concluded that this study shows that physicians are aware  of the importance of antimicrobial prophylaxis  before surgical procedures.

 

However  further efforts are needed to ensure the implementation of the of the standard SAP guidelines in Jordanian  hospitals.9

 

V Goede et al conducted the study on Evaluation of prophylactic antibiotic administration at the surgical ward of a major referral   hospital, Islamic republic on Iran, concluded that of 155 patient included in the  analysis ,98%received prophylactic antibiotic before surgery :according to ASHP guidelines, prophylaxis  needed in only 106 (68.4%) of these 106,only 8 patient s received the correct antibiotic regimen. the commonest regimens administered  were  cefazolin + gentamycin (47.6%), cefazolin (20.5%) and cefuroxime (8.5%). Antibiotic prophylaxis was continued  in 83% of cases, while this was necessary  in only 1 surgical procedure were all evaluate parameter  correct.10

 

The aim and objectives are to analyze and assess the useof prophylactic   antibiotic usage prior to surgery.

 

MATERIALS AND METHODS:

Sample size:  150 patients

 

INCLUSION CRITERIA:

·        Patient of both sex above 18 years of age subjected for surgery.

·        Patient undergoing surgery in departments like orthopedic, surgery, ophthalmology, dentistry, gynecology, ENT.

 

EXCLUSION CRITERIA:

·        Patient on long term antibiotic therapy.

·        Patient known case of antibiotic allergy.

·        Pregnant and lactating women.

 

STUDY DESIGN:

Prospective, single centered study.

 

DURATION: 

12 months.

 

All inpatients subjected for surgery is the surgery ward is included in the study. Patient details such as patient demographics (age, sex, diagnosis), nature of surgery, timing, antibiotics, type and class of antibiotic were noted. The study was conducted after obtaining informed consent from the patient, This study was approved by the ethics committee IEC/DOPV/2015/17.

 

RESULTS:

The following results were obtained where the date were collected from the patient profiles.

DISCUSSION:

Sayer I al-azzam et al quoted that there is more male patient subjected for surgery which is similar to our report which shows that around 62% of patients who undergone surgery are  male.9

 

V Goede et al quoted that there is more 50-65 age patient subjected for surgery which is similar report.shows that more patients who undergone surgery are between 50-60 years age.10

 

Shasin SK et al quoted that there is more appendectomy patients subjected for surgery which is similar to our report which shows   that appendectomy and hernia are most common surgeries undergone by patient.11

 

PA Ongom et al quoted that there is more aminoglycosides used in patients subjected for surgerywhich is similar report which shows that aminoglycosides and beta lactam antibiotic are the commonly used antibiotics for surgical prophylaxis.12

 

Our study showsthat there is more mono therapy patients subjected for surgerywhich is similar report.PA ongom et al quoted that there is more Gentamycin used in patients subjected   for   surgery which is similar to our report .12

 

Appropriateness have been evaluated in correction with ASHP guidelines for management of antimicrobials for surgical prophylaxis and almost 90% appropriateness is seen with the therapy.

 

CONCLUSION:

Surgical prophylaxis is an essential part of surgery with this study, we can help is designing apart of surgical kit necessary antibiotic for prevention the related nosocomial infection. We recommended for further research to classify specific antibiotics for specific pathogen
