Abstract:
Background: Post-operative anaemia is often a reflection of pre-operative pre-operative work-up and pre-operative anaemia. In addition. Post-operative anaemia is also determined by co-morbidities of patients prior to surgery. The prevalence of post-operative anaemia varies based on surgical specialties and the experience of the surgeon; prevalence rates as high as 85% have been recorded in orthopaedic surgeries. Aim: To determine the prevalence of post-operative anaemic in surgical patients at the Rivers State University Teaching Hospital (RSUTH). Method: This was a six months cross sectional study of the post-operative anaemia of patients who had operation at the Surgery and Obstetrics/Gyaecology departments of The Rivers State University Teaching Hospital. The permission for the study was granted by the head of department of obstetrics and gynaecology in conjunction with the head of .the hospital management. The yard stick for anaemia was packed cell volume less than 33% in line with the World Health Organization (WHO). A structured proforma was used to obtain information from patient’s case notes and analyzed using SPSS version 25. Result: Three hundred and eigthy subjects were recruited for the study. Males subjects were 150 (39.5%) while females were 230 (60.5%) respectively. The mean age was 31 years. One hundred and ninety nine (52.4%) were obstetrics and gynaecological surgeries while 181 (47.6 %) were non-gynaecological surgeries. The commonest indication for surgery was caesarean section representing 130 (34.2%) of the subjects. Two hundred and sixty six of the subjects (70%) had PCV less than 33%. One hundred and fifty two (40%) women had PCV less than 33% while 114 (30%) of the men had PCV less than 33%. Conclusion: The study revealed that prevalence of post-operative anaemia amongst surgical patients at RSUTH was 70 %. The post-operative anaemia amongst women was worrisome. The need to optimize patients prior to surgery cannot be over-emphasized to prevent morbidities and mortalities post-operative.

Abstract:
Introduction: In cardiac surgery, anaemia itself or combined with other risk factors has been found to be a major predictor for adverse outcome both preoperatively and postoperatively and even during extracorporeal circulation, but data about the specific tolerance of Coronary Artery Bypass Graft (CABG) patients for anaemia are conflicting and may in part be confounded by the effects of bypass surgery. Objectives: This study was performed in the National Institute of Cardiovascular Diseases (NICVD) to observe whether the early outcomes of Off-Pump CABG (OPCAB)were affected by pre-operative haematocrit levels. Methods: A total of 200 patients who underwent isolated OPCAB between January 2015 and December 2020 were retrospectively selected and purposively allocated into two groups: a)100 patients having preoperative anaemia and b) 100 patients without preoperative anaemia. Preoperative, per-operative and early post-operative variables were recorded, compiled and compared. Results: Preoperative characteristics were homogenously distributed between two groups other than haemoglobin level. Female patients had lower haemoglobin in each group. More patients of anaemic group required intraoperative and postoperative blood transfusion. The amount of blood loss and transfused blood products was also higher in anaemic patients. The ventilation time, length of ICU and post-operative hospital stay were significantly higher among anaemic patients. Among the post-operative complications, only the incidence of renal dysfunction was significantly higher among anaemic patients. Conclusion:This study has showed that anaemic patients undergoing OPCAB had an increased risk of postoperative adverse events. Importantly, the extent of preexisting comorbidities substantially affected perioperative anaemia tolerance. Therefore, preoperative risk assessment, optimization and subsequent therapeutic strategies, such as blood transfusion, should take into account both the individual level of preoperative haemoglobin and the extent of concomitant risk factors.

Abstract:
INTRODUCTION Pre-operative anaemia is well recognised in patients presenting with colorectal cancer (CRC). While the benefits of long-term FeSO4 supplementation on Fe deficiency anaemia are well established, it is not known if short-course supplementation (2–3 weeks) impacts significantly on pre-operative haemoglobin (Hb) levels. This study examines the impact of short-term, oral FeSO4 supplementation on patients undergoing surgery for CRC. PATIENTS AND METHODS All patients with CRC presenting to a single surgeon were included. At diagnosis, baseline Hb and blood film were checked on all patients who then received 200 mg tds of FeSO4. Haemoglobin was rechecked pre-operatively and daily postoperatively. Patients requiring pre-operative blood transfusions were excluded from analysis. RESULTS Between 1 January 2004 and 31 December 2006, 117 patients were identified, 14 of whom were excluded. Patients received a median of 39 days’ treatment with FeSO4. Fifty-eight (56.3%) patients were anaemic at presentation gaining a mean of 1.73 g/dl (P < 0.001) from short-course FeSO4 supplementation. Right-sided tumours (lower mean Hb at presentation; P = 0.008) responded more to FeSO4 when compared to left-sided tumours (P < 0.017). Increase in Hb was unrelated to pathological stage. The transfusion rate for all curative resections was 0.69 units/patient. For the historical cohort (patients undergoing curative resection between 1 January 2001 and 31 December 2003), the mean transfusion rate fell from 1.69 units/patient. CONCLUSIONS Routine short-course supplementation with iron offers improved pre-operative Hb prior to surgery in CRC, especially in right-sided lesions and those with presenting anaemia.

Abstract:
Estimation of haemoglobin is still undertaken routinely before ENT surgery in many centres despite evidence that it is unnecessary, traumatic and expensive. The haemoglobin was estimated of all 372 children about to undergo ENT surgery in a busy district general hospital over a one year period. No child was noted to be clinically anacmic, and no child had a haemoglobin of less than 9 g/dl. Of 18 children with a haemoglobin level of 10.5 or less, 10 had their operations postponed and eight did not. There were no complications in the latter group. We can find no published evidence that operating on children with mild anaemia is unsafe. Ceasing routine pre-operative haemoglobin estimation would safely save an estimated £9000 per year in our unit.

Abstract:
BACKGROUND Iron deficiency anaemia (IDA) is a common condition in patients presenting for surgery and is found in up to 75% of non-cardiac surgical patients. Pre-operative haemoglobin (Hb) is a strong predictor of transfusion requirement and it should, as part of a comprehensive blood conservation approach, be optimised whenever possible. Treatment options for iron deficiency anaemia include oral and intravenous iron or red blood cell transfusion. That both, anaemia and red blood cell (RBC) transfusion expose the patient to unnecessary risks is supported by an ever-increasing body of evidence. Consequently, allogeneic RBC transfusion should be avoided whenever possible and alternative treatment modalities which optimize the patient’s own red cell mass should be exhausted. However, anxiety over the short and long term effects of intravenous iron have limited its more widespread use. Newer dextran-free compounds, however, provide a safer treatment option. OBJECTIVE The objective of this systematic review was to critically appraise, synthesise and present the best available evidence related to the effectiveness and economic aspects of intravenous iron administration on the correction of iron deficiency anaemia in the peri-operative period. DATA SOURCES A comprehensive search was undertaken on major electronic databases from 2001 to 2012. The search was conducted in English, German, Italian and Dutch. REVIEW METHODS Randomized controlled trials, quasi-randomized controlled trials and quasi-experimental studies were included in the review. Critical appraisal and data extraction were undertaken using the Joanna Briggs Institute critical appraisal instrument and the standard data extraction form for evidence of effectiveness. Anaemia correction was as defined by study authors RESULTS The quantitative component of the review identified two randomized controlled trials for inclusion. One study of 76 patients with menorrhagia evaluated the effectiveness of pre-operative intravenous (IV) iron compared with oral iron in anaemic patients scheduled for surgery – the nature of which was not reported, aiming for a 1 g/L haemoglobin increase preoperatively. The intravenous iron group had greater increases in the Hb level than the oral iron group (3.0 vs. 0.8 g/dl, respectively; p < 0.0001). One other study evaluated the effectiveness of pre-operative intravenous (IV) iron compared with placebo in patients with bowel cancer scheduled for resectional surgery, looking at haemoglobin changes between recruitment and day of admission. A small subgroup of these patients was anaemic but no difference was demonstrated in haemoglobin changes between the groups. One additional RCT was found examining the effectiveness of IV iron in cardiac surgical patients, but full text examination and appraisal revealed that the majority of patients enrolled in these studies were not anaemic. The search for the economic component of the review revealed no randomized controlled trials examining the cost effectiveness of preoperative correction of iron deficiency anaemia with intravenous iron CONCLUSIONS Our review found insufficient data to make firm conclusions about the efficacy of pre-operative intravenous iron administration for the correction of anaemia based on clinical trial settings. Neither could we establish firm conclusions on the potential cost savings due to intravenous iron supplementation. IMPLICATIONS FOR PRACTICE There is inadequate RCT evidence at present to guide clinical practice. IMPLICATIONS FOR RESEARCH Our study found insufficient data to make firm conclusions about the efficacy, safety and cost effectiveness of pre-operative intravenous iron administration for the correction of anaemia pre-operatively. Adequately powered RCTs are required that evaluate and report the efficacy, safety and potential cost savings of intravenous iron administration as a treatment modality for iron deficiency anaemia.

Abstract:
The transfusion of blood products may be required in the pre- and post-operative periods. However, there are inherent risks associated with blood transfusion, and there is not an unlimited supply of blood donations available. When a patient is anaemic, red blood cells should be transfused to maintain the oxygen-carrying capacity of blood. Blood products, such as platelets and fresh frozen plasma, are transfused to correct a coagulopathy and during major haemorrhage. This chapter reviews the physiology of blood, including ABO compatibility and rhesus status, the main blood products available for transfusion, and transfusion policy, including the treatment of major haemorrhage and the refusal of blood products.

Abstract:
Antenatal and intrapartum fetal monitoring aim to identify the beginning of the process of fetal hypoxia before irreversible fetal damage has taken place. Fetal movement counting by the mother has not been reported to be of any benefit. The biophysical profile score, incorporating ultrasound and fetal heart rate monitoring, has not been proven to reduce perinatal mortality in randomized trials. Doppler ultrasound allows the exploration of the perfusion of different fetal organ systems and provides data on possible hypoxia and fetal anaemia. Maternal uterine artery Doppler can be used to select women with a high risk for intrauterine growth restriction and pre-eclampsia but does not directly provide information on fetal status. Umbilical artery Doppler has been shown to reduce perinatal mortality significantly in high-risk pregnancies (but not in low-risk women). Adding middle cerebral artery Doppler to umbilical artery Doppler does not increase accuracy for detecting adverse perinatal outcome. Ductus venosus Doppler demonstrates moderate value in diagnosing fetal compromise; it is not known whether its use adds any value to umbilical artery Doppler alone. Cardiotocography (CTG) reflects the interaction between the fetal brain and peripheral cardiovascular system. Prelabour routine use of CTG in low-risk pregnancies has not been proven to improve outcome; computerized CTG significantly reduces perinatal mortality in high-risk pregnancies. Monitoring the fetus during labour with intermittent auscultation has not been compared to no monitoring at all; when compared with CTG no difference in perinatal mortality or cerebral palsy has been noted. CTG does lower neonatal seizures and is accompanied by a statistically non-significant rise in caesarean delivery. Fetal blood sampling to detect fetal pH and base deficit lowers caesarean delivery rate and neonatal convulsions when used in adjunct to CTG. Determination of fetal scalp lactate has not been shown to have an effect on neonatal outcome or on the rate of instrumental deliveries but is less often hampered by technical failure than fetal scalp pH. Analysis of the ST segment of the fetal ECG (STAN®) in combination with CTG during labour results in fewer vaginal operative deliveries, less need for neonatal intensive care, and less use of fetal blood sampling during labour, without a change in fetal metabolic acidosis when compared to CTG alone.
