    Comparison of blood loss in total knee replacement surgery with and without tranexamic acid: a prospective, time framed and observational analytical study
    (Medip Academy, 2024-06) Mandal, S.; Chatterjee, B. D.; Kar, A.; Agarwal, S.
    Background: Total knee replacement is one of the common orthopaedic procedures performed worldwide. Blood transfusion is one of the major requirements in TKR procedure due to the amount of blood loss during and after the procedure. We carried out a prospective study to determine the efficacy of tranexamic acid in controlling blood loss during TKR procedure. Methods: Study was conducted at a tertiary care centre, involving cases operated by a single surgeon. Study included 140 patients undergoing primary TKR for advance degenerative disease of knee and were divided into two groups of 70 each, one group that received tranexamic acid before surgery and another group that did not receive tranexamic acid before surgery. Patient with allergy to the drug, hepato/renal dysfunction, DVT, abnormal PT and INR were not included. Tranexamic acid was given intravenously as well as intra-articular. Results: Pre-operative haemoglobin ranged from 10.2 gm% to 14.4 gm% in the group getting tranexamic acid and from 10% to 14 % in the group not getting tranexamic acid. Post operatively haemoglobin varied from 8.4 gm% to 12.8 gm% in Group 1 and from 7.8 gm% to 12 gm% in Group 2. Difference of mean post-operative Hb (p=0.0045) and PCV (p=0.0024) in two groups was statistically significant. Conclusions: We concluded that administration of tranexamic acid reduces the blood loss as well as need of blood transfusion in a patient undergoing total knee replacement.

    Comparison of physical fitness in male and female medical students
    (Mrs Dipika Charan of MedScience (India) Publications, 2022-06) Satpathy, S; Nanda, RK; Kar, A.
    Background: Students entering medical college find it difficult to cope with the burden of studies and go into depression. They cannot maintain their study habits as before due to extreme tiredness and fatigue following their regular classes. Aim and Objectives: The present study aims to evaluate the physical fitness status of male and female medical students. Materials and Methods: A total of 70 students, 35 male and 35 female, were selected randomly from the first two phases of this college. Their age, height, weight, and BMI were recorded. Their resting pulse rate was recorded after 15 min of resting. Then, each was made to undergo the Modified Harvard Step Test for 5 min or till exertion. Then, their immediate post-exercise pulse rate was recorded. VO2max was calculated and compared to find the physically fit group. Results: We found from the study that female students were similar to males in age, weight, and resting pulse rate. The height and maximum pulse rate post-exercise are more in males and BMI more in females and VO2max was found more in males. Conclusion: The male students are more physically fit than females and can cope with the different strenuous situations better than females. Females need to do regular exercise to increase their fitness.

    Knowledge-practice gap in breastfeeding and the factors influencing it among the urban mothers attending the immunization clinic under a tertiary care hospital in eastern India
    (Medip Academy, 2023-09) Kar, S.; Singh, S.; Kar, A.
    Background: Breast milk is a complete food for the newborn. Timely introduction of breast milk and exclusive breast feeding till 6 months of age of a newborn, with proper positioning and adequate attachment to mother’s breast is encouraged as Initiation of breast feeding within the first hour after birth, prevents the newborn from the risk of morbidity and mortality. An effective improvement in mother’s self efficacy and understanding on breast feeding will be useful in meeting the nutritional goals of the child. Aim of study was to assess the knowledge, perception and practice among the mothers on breast feeding and the factors influencing their practice and to determine probable association of ideal infant weight with exclusive breast feeding. Methods: Descriptive cross-sectional study among 390 mothers attending the Immunization Clinic of Kalinga Institute of Medical Sciences, Bhubaneswar. They were assessed if they breast fed infant by following the ideal positioning and proper attachment to breast and for their knowledge, perception and practices of breast feeding. Analysis was done using STATA-17. Results: Good knowledge, perception and practice of breast feeding was present among 88.2%, 83.5% and 69.8% mothers, respectively. Association between ideal weight of baby and proper breast feeding technique was found. Knowledge was more positively related to practice, than to perception. Conclusions: Children who have been exclusively breast fed, had the right weight for age. Mother and other family members must be aware of proper technique, adequacy and frequency of breast feeding for the best nourishment of the newborn.
