Background: Despite the advances made in asepsis, antimicrobial drugs, sterilization and operative techniques, surgical site infection (SSI) continues to be a major problem in all branches of surgery in the hospitals. However, there is no infection control policy that runs effectively in our country. Aim:This study was designed to see the correlation among sterilization, antibiotic resistance and malnutrition with surgical site infection in a tertiary level hospital. Methods: This cross-sectional observational study was conducted in the Department of Surgery, Shaheed Suhrawardy Medical College and Hospital. Informed written consent, detailed history, physical examination and necessary investigations were performed. Total 160 admitted patients undergoing different surgical procedure were included in this study, irrespective of their age, sex, race and ethnic group. Data were collected by using a semi-structured questionnaire. Collected data were analyzed by the SPSS 25. Results: Average age of all patient was 36.10±12.15 years (range: 13-65 years), wherein maximum patients were aged <40 years, male gender (56.3%), had normal BMI (61.3%) and non-smoker (62.07%). About 1/4th patients had diabetes mellitus. Maximum patients had undergone abdominal surgery (34.4%) followed by orthopaedic and traumatology (20.6%),General surgery other than abdominal surgery (18.8%), Neurosurgery (13.8%), Vascular surgery (12.5%). Pre-operative waiting period for surgery was <3 days in most of the cases (48.8%), followed by 3-7 days (31.3%) and >7 days (20%). Mean operation duration was 1.49±0.73 hours. Twenty-nine patients (18%) developed SSI, of which 7% had deep incisional SSI, 6% had superficial incisional SSI and 5% had organ/space SSI. SSI culture reports showed that majority (93.1%) had positive culture growth, wherein 66.7% had single microorganism and rest 33.3% had multiple growth. Staphylococcus aureus (34.48%) was the most frequently found microorganism. surgical team sterility was properly maintained in maximum surgical procedures (71.9%). Besides, OT room and surgical instruments were also properly sterilized in most of the cases (65.6% and 70%, respectively). Older age, abnormal BMI, smoking history, DM, longer pre-operative waiting period and operation duration was significantly associated with development of SSI. Besides, surgical team sterility, OT room sterility and Instrument sterility were not properly maintained in most of the surgical procedures among SSI patients (65.52%, 68.97% and 58.62%, respectively). Conclusion: Abnormal BMI (underweight and overweight or obese) and poor sterilization had significant association with development of SSI. However, further studies are needed to establish and use the findings. J Shaheed Suhrawardy Med Coll 2021; 13(2): 143-149

This prospective observational comparative study was conducted in department of Obstetrics and Gynaecology (OBGyn) of Shaheed Suhrawardy Medical College Hospital (ShSMCH), Dhaka. It was carried out from April 2019 to September 2019. The objectives was to compare the feto-maternal outcome of postdated pregnancy (40+1- 41+6 weeks) with pregnancy at term(37-40 weeks). Pregnant women admitted in ShSMCH with or without labour pain were considered as study population. Following ethical clearance from the local ethical committee and written informed consent, 59 cases of post-dated pregnancy (case) and 59 cases of term pregnancy (control) were included inthis study. Cases and control were selected by random sampling method according to inclusion and exclusion criteria. Inclusion criteria were: 1) Patients who have excellent EDD(dated by early ultrasonogram) , 2) Patients having regular menstrual cycle prior to present pregnancy and can remember exact LMP, 3) Postdated pregnancy as case and pregnancy at term as control. Exclusion criteria were: 1) Patients with eclampsia, systemic hypertension, heart disease, diabetes mellitus and renal disease, 2) Patients with multiple gestation and any congenital anomaly, 3) Pregnancy occurred during lactational amenorrhoea, 4) Pregnancy with veneral disease, 5) pregnancy with blood group incompatibility. Data were collected with a pre-designed structured questionnaire. A full assessment were done by history[age, occupation, menstrual and obstetric history, medical, surgical and family history, antenatal care(ANC)], physical examination (general, abdominal and vaginal) and ultrasonogram (USG) to assess gestational age and liquor volume. After proper counselling, induction of labour given to patients without labour pain and fetal distress. Mode of delivery, post-delivery maternal and fetal outcome and complication were recorded.This study showed that maximum number of patients in term pregnancy (control) belonged to age group (21-30 years) [control 71.2%, case 62.7%] and in post-dated pregnancy (case) belonged to >30 years [control 15.5%, case 23.7%]. In both groups, maximum number of women were housewives, control 48(81.4%), case 46(78%) and service-holder 11(18.6%) in control, 13 (22%) in case. In control group 36 (61%) were primi-gravida and 23 (39%) were multi-gravida. In case group 29(49.2%) were primi-gravida, 30(50.8%) multi-gravida. Family history of post-dated pregnancy were present in 14(23.7%) of control group and 13(22%) of case group. Most of the women of both control (93.2%) and case (89.8%) received regular ANC. Large fetus were seen in 6(10.2%) of control and 9(15.3%) of case group. Vertex was common presenting feature in both control (94.9%) and case (88.1%). Liquor volume was adequate in maximum number of women of both control (69.5%) and case (62.7%) group. Uterine irritability was present in 16(27.1%) of control and 17 (28.8%) of case group. Associated complication, such as CPD and elderly primi were present in 10 (16.9%) of control and 9 (15.3%) of case group. Induction of labour was required in 33(55.9%)of control and 41 (69.5%) of case group. Normal vaginal delivery was achieved in 41 (69.5%) of control and in 33 (55.9%) of case group women. LSCS required in 18 (30.5%) of control and 25 (42.4%) of case group women. Cause of LSCS is fetal distressin (54.5%) of control and (42.4%) of case group. Post-operative complication were more in case (16.9%), versus (3.4%) in control. Fetal complication were more in case group (22%), versus control (6.8%) regarding birth asphyxia, RDS, neonatal jaundice, neonatal septicemia, meconium aspiration syndrome, macrosomia and neonatal death. So this study showed that maternal and fetal perinatal morbidiy were quite high in post-dated pregnancy. There is scope for further improvement of clinical care practices of post-dated pregnant womenwith acceptable maternal and fetal outcome. J Shaheed Suhrawardy Med Coll 2021; 13(2): 130-136
