Abstract
Postoperative neurological disorders, including postoperative delirium (POD), postoperative cognitive dysfunction (POCD), postoperative covert ischemic stroke, and hemorrhagic stroke, are challenging clinical problems in the emerging aged surgical population. These disorders can deteriorate functional outcomes and long‐term quality of life after surgery, resulting in a substantial social and financial burden to the family and society. Understanding predisposing and precipitating factors may promote individualized preventive treatment for each disorder, as several risk factors are modifiable. Besides prevention, timely identification and treatment of etiologies and symptoms can contribute to better recovery from postoperative neurological disorders and lower risk of long‐term cognitive impairment, disability, and even death. Herein, we summarize the diagnosis, risk factors, prevention, and treatment of these postoperative complications, with emphasis on recent advances and perspectives.

Potential cardiovascular adverse events when phenylephrine is combined with paracetamol: simulation and narrative review. Eur J Clin Pharmacol 2015; 71:931-8. [PMID: 26022219 PMCID: PMC4500855 DOI: 10.1007/s00228-015-1876-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2015] [Accepted: 05/20/2015] [Indexed: 11/23/2022]
Abstract
Background Increased bioavailability of phenylephrine is reported when combined with paracetamol in over-the-counter formulations for the symptomatic treatment of the common cold and influenza. Such formulations could increase phenylephrine-related cardiovascular adverse events particularly in susceptible individuals. Quantification of the effect of phenylephrine concentration on blood pressure allows simulation of potential adverse combination therapy effects. Methods MEDLINE and EMBASE databases were searched for papers discussing or describing any adverse effect, hypersensitivity or safety concerns related to phenylephrine alone or in combination with other drugs. The pharmacodynamic relationship between plasma phenylephrine concentration and mean arterial blood pressure was characterized using published observations of blood pressure changes after ophthalmic eye drops. The resulting pharmacokinetic and pharmacodynamic parameters were then used to predict mean arterial blood pressure (MAP) changes in that population if given an oral combination of phenylephrine and paracetamol. Results There were 1172 papers identified for examination. Forty-seven reports fulfilled the inclusion criteria. Increases in blood pressure and decreases in heart rate have been reported with doses over 15 mg. It has been estimated that a 20-mmHg increase in systolic blood pressure would occur with an oral dose of 45 mg phenylephrine in normotensive healthy people. Those taking monoamine oxidase inhibitors report increased systolic blood pressure of greater than 60 mmHg. Blood pressure and heart rate changes are potentiated in patients with underlying hypertension. Simulation showed a modest increase in MAP when phenylephrine 10 mg was co-administered with paracetamol 1 g (4.2 vs 12.3 mmHg). Conclusions Combination paracetamol phenylephrine oral therapy has potential to increase blood pressure more than phenylephrine alone in those with cardiovascular compromise.

Tark BE, Messe SR, Balucani C, Levine SR. Intracerebral hemorrhage associated with oral phenylephrine use: a case report and review of the literature. J Stroke Cerebrovasc Dis 2014; 23:2296-300. [PMID: 25156786 DOI: 10.1016/j.jstrokecerebrovasdis.2014.04.018] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2014] [Revised: 04/02/2014] [Accepted: 04/05/2014] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Prior reports have linked both ischemic and hemorrhagic stroke to use of sympathomimetic drugs including phenylephrine. The purpose of this study is to describe the first case, to our knowledge of intracerebral hemorrhage (ICH) after oral use of phenylephrine and to systematically review the literature on phenylephrine and acute stroke. METHODS A case report and review of the literature. RESULTS A 59-year-old female presented with thunderclap headache, right hemiparesis, aphasia, and left gaze deviation. Head computed tomography (CT) showed a left frontal ICH with intraventricular and subarachnoid extension. She had no significant past medical history. For the previous 30 days, the patient was taking multiple common cold remedies containing phenylephrine to treat sinusitis. CT and magnetic resonance angiography showed no causative vascular abnormality. Catheter cerebral angiography supported reversible cerebral vasoconstriction syndrome (RCVS). Phenylephrine was determined to be the most likely etiology for her hemorrhage. A review of the literature, found 7 cases describing phenylephrine use with acute stroke occurrence: female, 5 of 7 (71%); route of administration, nasal (n = 3), ophthalmic (n = 2), intravenous (n = 1), intracorporeal injection (n = 1). Stroke types were subarachnoid hemorrhage (n = 5), ICH (n = 4), and ischemic (n = 1). One case reported RCVS after phenylephrine use. CONCLUSIONS It is scientifically plausible that phenylephrine may cause strokes, consistent with the pharmacologic properties and adverse event profiles of similar amphetamine-like sympathomimetics. As RCVS has been well described in association with over-the-counter sympathomimetics, a likely, although not definitive, causal relationship between phenylephrine and ICH is proposed.
