“…A detailed search of literature revealed little information as to the timing of postoperative haematocrit following surgery in Obstetrics and Gynaecology. This has been corroborated by authors in other faculties (4,6). In our institutions, we found out that there was an inconsistent timing of post-operative haematocrit; with most measurements being done either on postoperative (POD) 1 or 2.…”

“…This could be due to ongoing blood loss from the wound site, further dilution by intravenous fluids, timing of equilibration of the blood after acute blood loss and atimes inflammatory response to surgery (4). Various studies have shown that reequilibration of blood after acute blood loss or transfusion usually occurs within 24 hours (6,10,11). This implies that the difference noticed was due to ongoing blood loss.…”

“…There are various methods of estimating blood loss following surgery; however, the haematocrit balance is believed to be the most reliable (4,6). The major drawback is that it is not helpful intraoperatively since equilibration would not have taken place (5).…”

“…The major drawback is that it is not helpful intraoperatively since equilibration would not have taken place (5). Nevertheless, measurement of haematocrit post operatively is believed to be part of good medical practice since it gives an inkling to intraoperative and immediate post-operative blood loss and the need for blood transfusion (4,6).…”

Background: Haemorrhage is a feared albeit common complication of surgery in Obstetrics and Gynaecology. Measurement of haematocrit post operatively is believed to be part of good medical practice since it gives an inkling to intraoperative and immediate post-operative blood loss and the need for blood transfusion. The objective of the study is to determine if there was any difference between haematocrit values gotten on day 1 and 2 and also to determine the optimal time for the post-operative haematocrit check. Methods: One thousand patients who had surgery in the department of Obstetrics and Gynaecology of LAUTECH Teaching Hospital (LTH) and Bowen University Teaching Hospital (BUTH), Ogbomoso were recruited. Capillary blood samples were obtained at 24hours and 48 hours post operatively. The haematocrit was determined using a 24 place micro haematocrit centrifuge and the values checked using a haematocrit reader. Frequency tables and charts were made and results were tested for significance with level of significance (x) set at 0.05. Results: The mean age of the patients was 32.88±9.45, with a modal age group of 21-30years. The commonest obstetric surgery done was caesarean section (60.6%) while the commonest gynaecological surgery was myomectomy (13.8%). There is a significant difference between the haematocrit values gotten on day one and two (p= 0.000). There was significant difference between the haematocrit values on both days and the unit the patient was managed; the type of surgery done and the age group of the patient. Conclusion: The haematocrit on postoperative day 2 is more representative of the blood loss.

“…Total knee arthroplasty (TKA) is the preferred treatment option for knee osteoarthritis. [6][7][8][9][10][11] As the technique has evolved, many different types of knee prostheses have emerged. However, the choice of prosthesis for TKA remains controversial as surgeons seek to provide patients with a stable implant that offers adequate range of motion (ROM) with minimal risk for postoperative complications or revision surgery.…”

There is an unmet need for a prosthesis designed according to the anatomical parameters of the Chinese population. This study aims to compare the use of a medial pivot (MP) implant or posterior cruciate ligament (PCL) substitution (posterior-stabilized [PS]) prosthesis for unilateral total knee arthroplasty (TKA) in a Chinese population. The medical records of patients undergoing unilateral TKA with an MP implant (Group A) or a PS prosthesis (Group B) at our institution between January 2010 and December 2011 were retrospectively reviewed. Patients were followed up for 5 years. Preoperatively and at the December 2016 postoperative follow-up, the Hospital for Special Surgery scoring system (HSS knee score) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were measured to evaluate TKA outcomes. This study included 49 patients in Group A and 51 in Group B. As of December 2016, there were no significant differences in the preoperative/postoperative changes in any category of the HSS knee score or WOMAC score between the groups. There were no postoperative complications in either group during the 5-year follow-up. There were no periprosthetic infections or need for revision surgery. One patient in Group A experienced aching and a small amount of effusion in the articular cavity that was attributed to overexertion. In conclusion, there were no significant differences in midterm outcomes in Chinese patients receiving an MP implant or a PS prosthesis for unilateral TKA. These data suggest that the MP and PCL substitution design are safe and effective for unilateral TKA in China.

Background: Iron supplementation provides iron storage and facilitates the effective production of hemoglobin. The purpose of this study was to investigate the effect of early postoperative intravenous (IV) iron supplementation in different types of total knee arthroplasty (TKA) surgery. Methods: We retrospectively analyzed 863 patients who underwent TKA between September 2017 and September 2021. The IV iron (I) and non-IV iron (NI) groups were compared. Hemoglobin responders which is defined as patients who showed a change in hemoglobin level of ≥ 2 g/dL at six weeks of surgery compared to the baseline immediate postoperative hemoglobin level were identified and these were compared with non-responders. After logistic regression analysis, the patients were classified according to the surgery type (unilateral TKA, staged bilateral TKA and simultaneous bilateral TKA). A subgroup analysis was performed according to the comorbidity as Charleston Comorbidity Index (CCI). Results: The type of surgery and the rate of hemoglobin responders differed between the I- and NI-groups. The surgery type and iron supplementation significantly affected the hemoglobin responder in the logistic regression model. In each surgery type, the hemoglobin drop of the I-group were generally lower in the second and sixth weeks than in the NI-group. It was also effective in reducing the hemoglobin drop on the first day of the second surgery in staged bilateral TKA. In addition, the number of hospital days was lower in the IV iron supplementation group who underwent staged bilateral TKA. CCI did not affect hemoglobin responder, hemoglobin drop, and transfusion rate in both I- and NI-groups. Conclusions: Postoperative IV iron supplementation affected the outcome of hemoglobin responders. In addition, it reduced early postoperative hemoglobin drop. However, iron supplementation did not affect the transfusion rate, complications and clinical outcome, regardless of the type of surgery. Level of evidence: Level III, case-control study. Key words: Knee, total knee arthroplasty, hemoglobin, iron supplementation, surgery type, hemoglobin responder.
