Midwest Surgical AssociationCase cohort study of risk factors for post-thyroidectomy hemorrhage
Section snippets
Methods
A retrospective case cohort study of all patients with post-thyroidectomy hemorrhage between December 2008 and August 2014 was performed. During this study period, 16 patients were identified with post-thyroidectomy bleeding requiring reoperation. The hemorrhage group was compared with a stratified randomized sample of 32 patients that did not develop postoperative hemorrhage. Patients in this group were randomly selected to obtain a 2:1 ratio of nonhemorrhage to hemorrhage and were controlled
Results
For the time period of our study, 682 thyroid surgeries were performed. Overall 16 of 682 of these patients developed postoperative hemorrhage requiring reoperation, an incidence of 2.3%.
Within the hemorrhage group, median age was 54.5 (range 28 to 77). Overall 14 of 16 were female, and 2 of 16 were male. Overall 8 of 16 were Caucasian, and 8 of 16 were African American. The most common indication for surgery was goiter, and the most common operation performed was total thyroidectomy. A total
Conclusions
Several potential risk factors for post-thyroidectomy bleeding were analyzed. The parameter with the greatest association was the presence of postoperative hypertension, which was present in 81% of our hemorrhage population, and demonstrated statistically significant association with development of postoperative hemorrhage, as well as greatly increased the risk of developing postoperative hemorrhage. The most frequently encountered symptom was swelling, which was experienced by 81% of our

Early postoperative blood pressure and blood loss after cardiac surgery: A retrospective analysis
2017, Intensive and Critical Care NursingCitation Excerpt :Of note, the incidence and frequency of hypertensive MAP was not analysed. Samona and colleagues recently reported postoperative systolic blood pressure >150 mmHg as the strongest risk factor for bleeding in a retrospective analysis of thyroidectomy patients (Samona et al., 2016). Morton and colleagues have described a 39% risk increase for postoperative haemorrhage for every 10 points of the highest blood pressure after thyreoid surgery (Morton and Vandal, 2015).
Does Practice Type Determine the Complexity of Patients Encountered for Orthognathic Surgery?
2016, Journal of Oral and Maxillofacial SurgeryCitation Excerpt :The perioperative and postoperative effects of comorbidities have been acknowledged in multiple studies. HTN leads to peri- and postoperative bleeding problems.15 DM leads to wound-healing complications and infections, and perioperative control of blood glucose levels is often difficult because of the body's stress response to surgery.16
