Neurosurgical procedures in Jehovah's Witnesses: an increased risk?

Surgical Experience of Posterior Fossa Meningioma in a Jehovah's Witnesses Patient

Unexpected bleeding is a common complication that can occur during surgery. This unexpected bleeding can be managed by checking the patients' preoperative hemodynamic state or by autologous transfusion of an appropriate volume during surgery depending on the amount of blood loss and hemodynamic condition. However, patients like Jehovah's Witnesses, who refuse autologous transfusions for religious reasons even in life-threatening situations, present a predicament for treating physicians. The author reports on a large meningioma on the posterior fossa of a Jehovah's Witness patient who underwent surgery without autologous blood transfusion. There were no major problems other than the fear of unexpected massive bleeding. The surgeon's attention and efforts to minimize bleeding during surgery seemed to be the most important factors for success.

How to approach orthognathic surgery in patients who refuse blood transfusion

Background

Some patients who need surgery refuse a blood transfusion because of their religious beliefs or concerns about blood-borne infections. In recent years, bloodless surgery has been performed successfully in many procedures, and is therefore of increasing interest in orthognathic surgery.

Methods

Ten Jehovah’s Witnesses who visited our bloodless surgery center for orthognathic surgery participated in this study. To maintain hemoglobin (Hb) levels above 10 g/dL before surgery, recombinant erythropoietin (rEPO) was subcutaneously administered and iron supplements were intravenously administered. During surgery, acute normovolemic hemodilution (ANH) and induced hypotensive anesthesia were used. To elevate the Hb levels to >10 g/dL after surgery, a similar method to the preoperative approach was used.

Results

The 10 patients comprised three men and seven women. Their average Hb level at the first visit was 11.1 g/dL. With treatment according to our protocol, the average preoperative Hb level rose to 12.01 g/dL, and the average Hb level on postoperative day 1 was 10.01 g/dL. No patients needed a blood transfusion, and all patients were discharged without any complications.

Conclusions

This study presents a way to manage patients who refuse blood transfusions while undergoing orthognathic surgery. rEPO and iron supplementation were used to maintain Hb levels above 10 g/dL. During surgery, blood loss was minimized by a meticulous procedure and induced hypotensive anesthesia, and intravascular volume was maintained by ANH. Our practical approach to orthognathic surgery for Jehovah’s Witnesses can be applied to the management of all patients who refuse blood transfusions.

Risk associated with perioperative red blood cell transfusion in cranial surgery

We assessed the impact of intra- and postoperative RBC transfusion on postoperative morbidity and mortality in cranial surgery. A total of 8924 adult patients who underwent cranial surgery were identified in the 2006-2011 American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database. Patients undergoing a biopsy, radiosurgery, or outpatient surgery were excluded. Propensity scores were calculated according to demographic variables, comorbidities, and preoperative laboratory values. Patients who had received RBC transfusion were matched to those who did not, by propensity score, preoperative hematocrit level, and by length of surgery, as an indirect measure of potential intraoperative blood loss. Logistic regression was used to predict adverse postoperative outcomes. A total of 625 (7%) patients were transfused with one or more units of packed RBCs. Upon matching, preoperative hematocrit, length of surgery, and emergency status were no longer different between transfused and non-transfused patients. RBC transfusion was associated with prolonged length of hospitalization (OR 1.6, 95% CI 1.2-2.2), postoperative complications (OR 2.8, 95% CI 2.0-3.8), 30-day return to operation room (OR 2.0, 95% CI 1.3-3.2), and 30-day mortality (OR 4.3, 95% CI 2.4-7.6). RBC transfusion is associated with substantive postoperative morbidity and mortality in patients undergoing both elective and emergency cranial surgery. These results suggest judicious use of transfusion in cranial surgery, consideration of alternative means of blood conservation, or pre-operative restorative strategies in patients undergoing elective surgery, when possible.

Blood use in neurosurgical cases at the university hospital of the west indies

OBJECTIVE

Many neurosurgical cases are done without the need for blood transfusion, yet blood is unnecessarily cross-matched, resulting in wasted resources. This study was undertaken to document and compare the number of units of blood components requested, cross-matched and transfused in neurosurgical cases at the University Hospital of the West Indies (UHWI).

METHODS

A prospective, observational study was undertaken over one year. Data collected for each patient included demographic information, relevant perioperative data, and blood banking data including blood components requested, cross-matched and transfused. Data were analysed using SPSS version 16.

RESULTS

Data were analysed on 152 patients, 71 females (46.7%) and 81 males (53.3%). The mean age was 48.7 ± 19.6 years and 100 of the procedures were done electively (65.8%). Blood components were ordered in 114 (75%) cases, red cells more commonly in 113 (74.3%) patients, and plasma in 19 (12.5%) patients. Overall, 20 patients (13.2%) were transfused. Most patients (90.9%) needed one to two units of blood. Of the 236 units of blood components that were cross-matched or prepared, only 62 were transfused. The cross-match/preparation to transfusion ratio (CTR/PTR) was 6.00 for red cells and 1.31 for plasma. Preoperative haemoglobin ≤ 10.0 g/dL (p = 0.001), estimated blood loss of ≥ 1 litre (p < 0.001), higher American Society of Anesthesiologists (ASA) physical status score (p < 0.03) and a resident as lead surgeon (p < 0.05), were significant predictors of blood transfusion.

CONCLUSION

The transfusion rate was low with a high cross-match to transfusion ratio, suggesting that less cross-matching is needed. A new approach to blood ordering for neurosurgical cases is recommended.

Surgical management in treatment of Jehovah's witness in trauma surgery in Indian subcontinent

The Jehovah's Witness religion is a Christian movement, founded in the US in the 1870s, with 7 million followers worldwide with only 0.002% in India. There is minimal to complete absence of awareness about the existence of this community in our society. Astonishing is that fact that among medical professionals, there is almost no awareness about this unique population, regarding the fact that they completely refuse of blood transfusion even if it leads to their death. This is integral to their faith. Besides legal and ethical issues in treating these group of patients, the biggest challenge exist even in the western world is their management in trauma scenario where few options exist. We have discussed the issues and recommendations in management in trauma scenario in our Indian subcontinent.

Risk-adjusted clinical outcomes in patients enrolled in a bloodless program

BACKGROUND

Although clinical outcomes have been reported for patients who do not accept allogeneic blood transfusion (ABT), many previous studies lack a control group, fail to use risk adjustment, and focus exclusively on cardiac surgery.

STUDY DESIGN AND METHODS

We report a risk-adjusted, propensity score-matched, retrospective case-control study of clinical outcomes for inpatients who did not accept ABT (bloodless, n = 294) and those who did accept ABT (control, n = 1157). Multidisciplinary specialized care was rendered to the bloodless patients to conserve blood and optimize clinical outcomes. Differences in hemoglobin (Hb), mortality, five morbid outcomes, and hospital charges and costs were compared. Subgroups of medical and surgical patients were analyzed, and independent predictors of outcome were determined by multivariate analysis.

RESULTS

Overall, mortality was lower in the bloodless group (0.7%) than in the control group (2.7%; p = 0.046), primarily attributed to the surgical subgroup. After risk adjustment, bloodless care was not an independent predictor of the composite adverse outcome (death or any morbid event; p = 0.91; odds ratio, 1.02; 95% confidence interval, 0.68-1.53). Discharge Hb concentrations were similar in the bloodless (10.8 ± 2.7 g/dL) and control (10.9 ± 2.3 g/dL) groups (p = 0.42). Total and direct hospital costs were 12% (p = 0.02) and 18% (p = 0.02) less, respectively, in the bloodless patients, a difference attributed to the surgical subgroup.

CONCLUSIONS

Using appropriate blood conservation measures for patients who do not accept ABT results in similar or better outcomes and is associated with equivalent or lower costs. This specialized care may be beneficial even for those patients who accept ABT.
