Increased bleeding tendency is associated with the use of selective serotonin reuptake inhibitors. In this study, we report a case of perioperative bleeding in patient on selective serotonin reuptake inhibitors. The management options for such cases are discussed.

| Case presentation|| |
A female patient aged 48 years was admitted to the ICU for postoperative care because of intraoperative bleeding during total abdominal hysterectomy. The patient was known to be diabetic and on oral hypoglycemics; she was also suffering from generalized anxiety disorder [was on paroxetine 20 mg and selective serotonin reuptake inhibitors (SSRIs) for 3 months]. The patient’s laboratory analysis on admission showed the following parameters − hemoglobin 11.2 g%, prothrombin time 14.3, partial thromboplastin time 34.6, international normalized ratio 1.2, and platelets 220 000 (all within the normal range)
During the surgery, the patient lost excessive amounts of blood (unexplained by the surgery), and the blood oozed to the surgical field. Intraoperative complete blood count showed hemoglobin levels of 7.5 g% and platelets of 188 000. Resuscitation was initiated, and blood product replacement was carried out. The patients remained in the ICU until she received a total of 3 U packed red blood cells+2 U fresh frozen plasma.
- Is there a correlation between SSRI and increased bleeding tendency; if so, what is the mechanism involved and how do we manage it?
- Are there any recommendations to stop such drugs in the perioperative period?

| Discussion|| |
Perioperative blood transfusions increase the relative risk of postoperative infections and are associated with significant morbidity and mortality . A vital indication for blood transfusions is major perioperative blood loss . The amount of perioperative blood loss can be negatively influenced by the use of drugs that increase bleeding tendency . Increased bleeding tendency is associated with the use of SSRIs. These reports are mainly from observational, retrospective studies that do not prove causality ,,.
Antidepressant medications are commonly used for many psychiatric illnesses including major depressive disorder, generalized anxiety disorder, social anxiety disorder, panic disorder, obsessive compulsive disorder, bulimia nervosa, post-traumatic stress disorder, premenstrual dysphoric disorder, borderline personality disorder, and nicotine dependence .
Several studies have shown that the use of SSRIs is associated with an increased risk of gastrointestinal bleeding ,. Moreover, many studies have addressed the association between SSRI use and perioperative blood loss .
Over the years, numerous case reports and case–control studies have suggested that SSRI use is associated with an increased risk of bleeding. The bleeding pattern varied from minor bleeding to spontaneous gastrointestinal bleeding and excessive perioperative hemorrhage . One study showed that SSRI users who underwent orthopedic surgery had nearly a four-fold increased risk of requiring blood transfusion . In addition, large population-based, case–control studies have consistently shown an increased incidence of upper gastrointestinal bleeding associated with SSRI use, especially when comedicated with NSAIDs and aspirin . In 2014, a retrospective study on SSRI users undergoing hip surgery showed that they had an increased risk for blood transfusion during hospitalization. The study considered SSRI use as a potential risk indicator for increased blood loss in patients admitted for hip surgery .
The underlying pathophysiological mechanisms of increased bleeding tendency after SSRIs use have been previously studied, and significant changes in platelet function related to SSRI use are consistently reported, such as prolongation of platelet function assay (PFA) closure time and a decrease in plasma β-thromboglobulin and plasma platelet factor 4 ,. Furthermore, SSRIs decrease the reuptake of serotonin, thereby increasing serotonin levels in the synapses of the central nervous system promptly, and after prolonged exposure they also induce a gradual downregulation and desensitization of serotonin autoreceptor activity in serotonergic cell bodies and terminals. These changes are considered to be linked to the improvement of depression with SSRIs. Serotonin transported into platelets is released from platelets in response to vascular injury, which in turn triggers vasoconstriction and platelet aggregation. As SSRIs inhibit the activity of serotonin reuptake transporters of the platelets, they lower the amount of serotonin available in the platelets. Therefore, serotonin depletion leads to suboptimal initiation of the coagulation cascade and causes prolongation of bleeding .
SSRIs affect platelet aggregation, which can be measured by a PFA. The PFA measures both platelet adhesion and aggregation (primary hemostasis) . SSRIs do not affect other bleeding parameters including the international ratio, partial thromboplastin time, or prothrombin time, which measures the enzymatic cascade leading to a fibrin clot. Alterations of the PFA in patients taking SSRIs compared with those on a nonserotonergic antidepressant have been demonstrated . Mago et al.  suggested that PFA should be evaluated before elective surgery in patients on SSRIs, although no data are present to define the benefits of this test in the presurgical setting.
Perioperative continuation of SSRIs is associated with increased blood loss. However, anesthesiologists should consider the increased risk of bleeding in combination with other patient or surgery factors, including the use of antiplatelet drugs such as clopidogrel or NSAIDs, pre-existing bleeding disorders, or intracranial surgery. Planned discontinuation of SSRIs 2 weeks before the operation in patients with high risk of bleeding or shifting to an antidepressant that does not inhibit or less potently inhibits serotonin reuptake (e.g. bupropion or mirtazapine) or obtaining a PFA can be considered.
