ABSTRACT
Bloodless surgery was introduced initially for the care of patients who
refused blood transfusion. Recently however, adverse outcome with blood
transfusion has been reported in virtually all subspecialties of surgery and
conversely, improved outcome with non-transfusion surgery. Thus blood
conservation is the standard of care because it is evidence-based. Thyroid
surgery is historically associated with blood loss, and a lower hemato-
crit would be expected postoperatively. We report a case of subtotal
thyroidectomy for a large simple multinodular goiter using planned
blood-conservation techniques tailored to the patient that resulted in
maintenance of a normal hematocrit throughout the perioperative period.
The patient received oral hematinics preoperatively, while acute normo-
volemic hemodilution and other techniques were used to minimize
intraoperative blood loss. The outcome was an optimized hematocrit
preoperatively, minimal blood loss intraoperatively, and hematocrit
which remained optimal on the third postoperative day and 3 weeks
postoperatively. No allogeneic blood was used at any stage. This suggests
that maintenance of normal hematocrit can be regarded as an achievable
goal in high-risk surgery through blood-conservation techniques. Avoid-
ing allogeneic blood transfusion is possible in a resource-poor setting,
where HIV prevalence is high and screening of blood may be suboptimal,
and it is the ideal clinical approach as demonstrated in this case report.
CASE REPORT
A 44-year-old woman presented at the Surgical Outpa-
tient Department with anterior neck swelling of 4-year
duration measuring 9 cm (vertical) ¥ 13 cm (transverse).
The swelling was bigger to the right of midline than to
the left and her trachea was deviated to the left.
However, she had neither pressure symptoms nor any
other symptoms. Clinical diagnosis of simple multi-
nodular goiter was made and thyroid function tests done
showed normal parameters. Her hematocrit was 34%.
She was offered subtotal thyroidectomy using blood-
conservation techniques and she consented. A blood-
conservation plan was drawn up and anesthesiologist’s
review sought. From the first outpatient visit the patient
was placed on oral ferrous gluconate 900 mg (105 mg
elemental iron) daily along with adjuncts (Vitamin C,
Vitamin B Complex, and Multivitamins). Six weeks later
