RESUMO
BACKGROUND: Perioperative ß-blocker therapy has been associated with increased risk of stroke. However, the association between ß-blocker initiation before the day of surgery and the risk of stroke is unknown. The authors hypothesized there would be no association between preoperative ß-blocker initiation within 60 days of surgery or chronic ß-blockade (more than 60 days) and the risk of stroke in patients undergoing major abdominal surgery. METHODS: Data on elective major abdominal surgery were obtained from the IBM (USA) Truven Health MarketScan 2005 to 2015 Commercial and Medicare Supplemental Databases. Patients were stratified by ß-blocker dispensing exposure: (1) ß-blocker-naïve, (2) preoperative ß-blocker initiation within 60 days of surgery, and (3) chronic ß-blocker dispensing (more than 60 days). The authors compared in-hospital stroke and major adverse cardiac events between the different ß-blocker therapy exposures. RESULTS: There were 204,981 patients who underwent major abdominal surgery. ß-Blocker exposure was as follows: perioperative initiation within 60 days of surgery for 4,026 (2.0%) patients, chronic ß-blocker therapy for 45,424 (22.2%) patients, and ß-blocker-naïve for 155,531 (75.9%) patients. The unadjusted frequency of stroke for patients with ß-blocker initiation (0.4%, 17 of 4,026) and chronic ß-blocker therapy (0.4%, 171 of 45,424) was greater than in ß-blocker-naïve patients (0.2%, 235 of 155,531; P < 0.001). After propensity score weighting, patients initiated on a ß-blocker within 60 days of surgery (odds ratio, 0.90; 95% CI, 0.31 to 2.04; P = 0.757) or on chronic ß-blocker therapy (odds ratio, 0.86; 95% CI, 0.65 to 1.15; P = 0.901) demonstrated similar stroke risk compared to ß-blocker-naïve patients. Patients on chronic ß-blocker therapy demonstrated lower adjusted risk of major adverse cardiac events compared to ß-blocker-naïve patients (odds ratio, 0.81; 95% CI, 0.72 to 0.91; P = 0.007), despite higher unadjusted absolute event rate (2.6% [1,173 of 45,424] vs. 0.6% [872 of 155,531]). CONCLUSIONS: Among patients undergoing elective major abdominal surgery, the authors observed no association between preoperative ß-blocker initiation within 60 days of surgery or chronic ß-blocker therapy and stroke.

BACKGROUND: The Caprini risk assessment model (RAM) stratifies surgical patients for prescription of post-discharge extended heparin prophylaxis to reduce post-operative venous thromboembolism (VTE) events. The average cost for treatment of a VTE event is $15,123. The 30-day post-operative VTE rate after benign esophageal procedures is < 0.8% per the Society of Thoracic Surgeons database. We hypothesized that the financial cost of selective extended prophylaxis in patients undergoing surgery for benign esophageal disease would exceed the cost of treating these rare events and therefore use of risk stratification for extended prophylaxis would not be beneficial. METHODS: All patients undergoing operations for benign esophageal pathology from July 2014 to May 2019 were reviewed. Patients designated as moderate or high risk for VTE were prescribed a 10- or 30-day post-operative course of extended prophylaxis with low-molecular weight heparin (LMWH). VTE and adverse bleeding events were recorded for the 60-day post-operative period. The cost of LMWH was provided by the institution pharmacy. RESULTS: Records from 154 patients were eligible for review. Caprini RAM was used for all patients with the following distribution of risk categories: low = 64.9% (100/154); moderate = 31.8% (49/154); and high = 3.2% (5/154). The average cost of extended prophylaxis at discharge for the moderate-risk group was $121.23, while the high-risk group was $446.46. There were no 60-day VTE or adverse bleeding events recorded. CONCLUSIONS: The majority of patients undergoing surgical therapy were at low risk of post-operative VTE event, with only 35% requiring extended VTE prophylaxis at time of discharge. When compared with the average cost of treatment for a VTE event, the cost of extended prophylaxis per patient in moderate or high-risk groups is substantially lower. In the era of cost-containment, risk stratification and extended prophylaxis may reduce healthcare costs and warrant future investigations.

OBJECTIVE: Bone morphogenetic protein (BMP) is a growth factor that aids in osteoinduction and promotes bone fusion. There is a lack of literature regarding recombinant human BMP-2 (rhBMP-2) dosage in different spine surgeries. This study aims to investigate the trends in rhBMP-2 dosage and the associated complications in spinal arthrodesis. METHODS: A retrospective study was conducted investigating spinal arthrodesis using rhBMP-2. Variables including age, procedure type, rhBMP-2 size, complications, and postoperative imaging were collected. Cases were grouped into the following surgical procedures: anterior lumbar interbody fusion/extreme lateral interbody fusion (ALIF/XLIF), posterior lumbar interbody fusion/transforaminal lumbar interbody fusion (PLIF/TLIF), posterolateral fusion (PLF), anterior cervical discectomy and fusion (ACDF), and posterior cervical fusion (PCF). RESULTS: A total of 1209 patients who received rhBMP-2 from 2006 to 2020 were studied. Of these, 230 were categorized as ALIF/XLIF, 336 as PLIF/TLIF, 243 as PLF, 203 as ACDF, and 197 as PCF. PCF (P < 0.001), PLIF/TLIF (P < 0.001), and PLF (P < 0.001) demonstrated a significant decrease in the rhBMP-2 dose used per level, with major transitions seen in 2018, 2011, and 2013, respectively. In our sample, 129 complications following spinal arthrodesis were noted. A significant relation between rhBMP-2 size and complication rates (χ2= 73.73, P = 0.0029) was noted. rhBMP-2 dosage per level was a predictor of complication following spinal arthrodesis (odds ratio = 1.302 [1.05-1.55], P < 0.001). CONCLUSIONS: BMP is an effective compound in fusing adjacent spine segments. However, it carries some regional complications. We demonstrate a decreasing trend in the dose/vertebral level. A decrease rhBMP-2 dose per level correlated with a decrease in complication rates.

Managing severe valvular heart disease with mechanical valve replacement necessitates lifelong anticoagulation with a vitamin K antagonist. Optimal anticoagulation intensity for patients with mechanical valves remains uncertain; current recommendations are inconsistent across guideline bodies and largely based on expert opinion. In this review, we outline the history of anticoagulation therapy in patients with mechanical heart valves and critically evaluate current antithrombotic guidelines for these patients. We conclude that randomized trials evaluating optimal anticoagulation intensity in patients with mechanical valves are needed, and that future guidelines must better justify antithrombotic treatment recommendations.

Importance: Prescription opioid use is common among patients with moderate to severe knee osteoarthritis before undergoing total knee replacement (TKR). Preoperative opioid use may be associated with worse clinical and safety outcomes after TKR. Objective: To determine the association of preoperative opioid use among patients 65 years and older with mortality and other complications at 30 days post-TKR. Design, Setting, And Participants: This cohort study used claims data from January 1, 2010, to December 31, 2014, from a random sample of US Medicare enrollees 65 years and older who underwent TKR. Based on opioid dispensing in 360 days prior to TKR, patients were classified as continuous (≥1 opioid dispensing in each of the past 12 months) or intermittent (any dispensing of opioids in the past 12 months but not continuous use) opioid users or as opioid-naive patients (no opioids dispensed in the past 12 months). Data analyses were conducted from October 3, 2017, to November 8, 2018. Main Outcomes and Measures: Primary outcomes included in-hospital mortality and 30-day post-TKR mortality, hospital readmission, and revision operation. Secondary safety outcomes at 30 days post-TKR included opioid overdose and vertebral and nonvertebral fracture. Multivariable Cox proportional hazards models estimated hazard ratios (HRs) and 95% CIs. Results: Of 316â¯593 patients (mean [SD] age, 73.9 [5.8] years; 214â¯677 [67.8%] women) who underwent TKR, 22â¯895 (7.2%) were continuous opioid users, 161â¯511 (51.0%) were intermittent opioid users, and 132â¯187 (41.7%) were opioid naive. In-hospital mortality occurred in 276 patients (0.09%). At 30 days post-TKR, 828 patients (0.26%) died, 16â¯786 patients (5.30%) had hospital readmission, and 921 patients (0.29%) had a revision operation. All primary and secondary outcomes occurred more frequently among continuous opioid users compared with opioid-naive patients. Compared with opioid-naive patients and after adjusting for demographic characteristics, combined comorbidity score, number of different prescription medications, and frailty, continuous opioid users had greater risk of revision operations (HR, 1.63; 95% CI, 1.15-2.32), vertebral fractures (HR, 2.37; 95% CI, 1.37-4.09), and opioid overdose (HR, 4.82; 95% CI, 1.36-17.07) at 30 days post-TKR. However, after adjusting covariates, there were no statistically significant differences in in-hospital (HR, 1.18; 95% CI, 0.73-1.90) or 30-day (HR, 1.05; 95% CI, 0.73-1.51) mortality between continuous opioid users and opioid-naive patients. Conclusions and Relevance: After adjusting for baseline risk profiles, including comorbidities and frailty, continuous opioid users had a higher risk of revision operations, vertebral fractures, and opioid overdose at 30 days post-TKR but not of in-hospital or 30-day mortality, compared with opioid-naive patients. These results highlight the need for better understanding of patient characteristics associated with chronic opioid use to optimize preoperative assessment of overall risk after TKR.

OBJECTIVES: Lung ultrasound can reliably diagnose pulmonary atelectasis. The object of this study is to determine the most efficient region to assess changes in atelectasis in children with congenital heart disease under general anesthesia. DESIGN: Randomized controlled trial. SETTING: Operating room at university-affiliated children's hospital. PATIENTS: Children between 3 months and 3 years old, scheduled for elective congenital heart disease surgery under general anesthesia. INTERVENTIONS: Forty children with congenital heart disease were randomly allocated to either a 5 cm H2O positive end-expiratory pressure group or a standard therapy control group. MEASUREMENTS AND MAIN RESULTS: Preoperative lung ultrasound was performed twice in each patient-after 1 and 15 minutes of mechanical ventilation. Atelectatic areas and B-lines were compared between two examinations. Different ultrasound regions were evaluated using Bland-Altman plots. The occurrence rate of atelectasis was much higher in inferoposterior lung regions (Scans 4-6) than in anterior and lateral regions (Scans 1-3). The median (interquartile range) lung ultrasound scores were lower in the positive end-expiratory pressure group than in the control group after treatment: 8 (3.3-9.8) versus 13 (8.3-17.5; p < 0.001). The atelectatic area was significantly decreased after treatment in the positive end-expiratory pressure group: 128 mm (34.5.5-213.3 mm) versus 49.5 mm (5.3-75.5 mm; p < 0.001). Bland-Altman plots revealed concordance between measurements in Scans 1-6 and those in Scans 4-6. In the posterior axillary line regions, changes in atelectatic area were significantly larger in the positive end-expiratory pressure group than in the control group (p = 0.03, 0.007, and 0.018). CONCLUSIONS: Lung ultrasound in inferoposterior lung regions may be more likely to reflect changes in atelectasis and save examination time; 5 cm H2O positive end-expiratory pressure may be useful in lung reaeration and can reduce, but not eliminate, atelectasis in children with congenital heart disease.

BACKGROUND: Heparin is routinely used in many cardiovascular procedures to prevent thrombosis. An antibody-mediated process, heparin-induced thrombocytopenia occurs in a small subset of patients exposed to heparin. Though some have suggested a recent increase in the incidence of heparin-induced thrombocytopenia, data on the impact of heparin-induced thrombocytopenia on costs and duration of stay after cardiac surgery is generally lacking. The present study aimed to assess national trends in the incidence and resource use associated with heparin-induced thrombocytopenia in cardiac surgical patients. METHODS: A retrospective cohort study was performed identifying adult cardiac surgery patients with a diagnosis of heparin-induced thrombocytopenia by using the 2009-2014 National Inpatient Sample Database. Association between development of heparin-induced thrombocytopenia and complications during hospitalization were evaluated using multivariate regression models. RESULTS: Of the 3,547,883 cardiac surgery patients, 13,943 (0.40%) were diagnosed with heparin-induced thrombocytopenia. Heparin-induced thrombocytopenia was associated with significantly longer median index duration of stay (elective 12 vs 6 days, urgent 17 vs 10 days; P < .001) and higher hospitalization costs (elective $56,230 vs $35,072, urgent $75,509 vs $42,789; P < .001). Independent predictors of heparin-induced thrombocytopenia included female sex (elective odds ratio 1.4, 95% confidence interval 1.01-1.03) and history of hypercoagulable condition (elective odd ratio 4.03, 95% confidence interval 1.8-8.9). After adjustment for baseline differences, heparin-induced thrombocytopenia was independently associated with increased risk of mortality (elective odds ratio 2.0, 95% confidence interval 1.3-3.1; urgent odds ratio 1.8, 95% confidence interval 1.3-2.5), neurologic (elective odds ratio 1.5, 95% confidence interval 1.2-1.9; urgent odds ratio 1.3, 95% confidence interval 1.1-1.6), infectious (elective odds ratio 2.4, 95% confidence interval 1.9-3.0; urgent odds ratio 1.6, 95% confidence interval 1.4-2.0), and respiratory (elective odds ratio 1.4, 95% confidence interval 1.2-1.5; urgent odds ratio 1.4, 95% confidence interval 1.2-1.5) complications. CONCLUSION: Based on this national analysis of adult cardiac surgical patients, the presence of heparin-induced thrombocytopenia was associated with higher odds of mortality and morbidity, greater costs, and longer duration of stay. Female gender, history of hypercoagulability, and heart failure, among others, are independent predictors of heparin-induced thrombocytopenia. These findings have significant implications in the era of value-based health care delivery. In addition to reducing unnecessary exposure to heparin, proper diagnosis and treatment are essential for favorable outcomes.

Inappropriate dosing of neostigmine for antagonism of neuromuscular blockade has been associated with postoperative pulmonary complications. We evaluated the effects of a quality improvement initiative tailored to optimise the use of neostigmine in antagonising neuromuscular blockade on postoperative pulmonary complications, costs and duration of hospital stay. The quality improvement initiative consisted of: a reduction in available neostigmine aliquot sizes; a cognitive aid; an educational component; and a financial incentive for the intra-operative documentation of train-of-four measurement before administration of neostigmine. We conducted a pre-specified analysis of data obtained in our quality improvement study. Additional analyses were conducted in a propensity-matched cohort. An interrupted time series design was used to discriminate between the intervention and a counterfactual scenario. We analysed 12,025 consecutive surgical cases performed in 2015. Postoperative pulmonary complications occurred in 220 (7.5%) of 2937 cases pre-intervention and 568 (6.3%) of 9088 cases post-intervention. Adjusted regression analyses showed significantly a lower risk of postoperative pulmonary complications (OR 0.73 (95%CI 0.61-0.88); p = 0.001), lower costs (incidence rate ratio 0.95 (95%CI 0.93-0.97); p < 0.001) and shorter duration of hospital stay (incidence rate ratio 0.91 (95%CI 0.87-0.94); p < 0.001) after implementation of the quality improvement initiative. Analyses in a propensity-matched sample (n = 2936 per group) and interrupted time series analysis (n = 27,202 cases) confirmed the findings. Our data show that a local, multifaceted quality improvement initiative can enhance the quality of intra-operative neuromuscular blocking agent utilisation, thereby reducing the incidence of postoperative pulmonary complications.

Angiogenesis plays a critical role in the growth, progression, and metastasis of numerous solid tumor types, and thus, antiangiogenic agents have been studied for many years as potential therapeutic agents. Many different antiangiogenic agents, including monoclonal antibodies and multi-targeted tyrosine kinase inhibitors (TKIs), have been approved for various oncology indications, and promising clinical activity has been demonstrated. However, some of these agents have also been associated with serious safety concerns. Because angiogenesis is an important step in the wound healing process, agents targeting the angiogenesis pathway may interfere with wound healing, thus increasing the risk of surgical wound complications, such as dehiscence, surgical site bleeding, and wound infection. Nevertheless, antiangiogenic agents can be safely used in the perioperative setting if oncologists and surgeons are educated on the biology and pharmacokinetics of these agents. This review discusses the available published literature regarding surgical complications associated with the use of antiangiogenic agents and provides updated clinical recommendations on the optimal timing between surgery and antiangiogenic therapy. Due to the paucity of data surrounding this topic, current and future clinical trials need to evaluate prospectively the potential risks for surgical complications associated with antiangiogenic therapies to establish specific guidelines for their safe and effective use within the surgical oncology community.

OBJECTIVE: Epirubicin (Epi) is a potent and effective drug for many malignant cancers with serious cardiotoxicity. Therefore, layer-specific two-dimensional speckle tracking echocardiography (2D-STE) was used to evaluate the longitudinal and circumferential systolic function of the left ventricular for the early detection of cardiotoxicity in this retrospective work. METHODS: Overall, 130 female patients with postoperative breast cancer who did not receive radiotherapy were classified into three groups: Group A (control group, n = 40) without any chemotherapy; Group B (n = 44) administered Epi at 180 ~ 240 mg/m2 ; and Group C (n = 46) administered Epi at ≥360 mg/m2 . Peak and global systolic longitudinal strains (GLS) in the total and endocardium, mid-myocardium, and epicardium were measured and calculated from apical four-chamber, apical two-chamber, and left ventricular long-axis views, respectively. Peak and global circumferential strains (GCS) in the total and endocardium, mid-myocardium, and epicardium were measured and calculated from mitral annulus, papillary muscle, and apical levels of the short-axis view, respectively. RESULTS: The total GLS and GLS of the endocardium in every view were significantly reduced in group C compared with both groups A and B (P < .05), but there was no significant difference between groups A and B (P > .05). The GLS of the epicardium and mid-myocardium in groups B and C were not significantly reduced (P > .05). There were no significant differences in the total GCS and layer-specific GCS of endocardium, mid-myocardium, and epicardium among the three groups (P > .05). CONCLUSIONS: Left ventricular longitudinal systolic dysfunction was detected. Moreover, an impaired endocardium was also detected in an early assessment by layer-specific 2DSTE.

Post-transplant diabetes mellitus (PTDM) is a frequent consequence of solid organ transplantation. PTDM has been associated with greater mortality and increased infections in different transplant groups using different diagnostic criteria. An international consensus panel recommended a consistent set of guidelines in 2003 based on American Diabetes Association glucose criteria but did not exclude the immediate post-transplant hospitalization when many patients receive large doses of corticosteroids. Greater glucose monitoring during all hospitalizations has revealed significant glucose intolerance in the majority of recipients immediately after transplant. As a result, the international consensus panel reviewed its earlier guidelines and recommended delaying screening and diagnosis of PTDM until the recipient is on stable doses of immunosuppression after discharge from initial transplant hospitalization. The group cautioned that whereas hemoglobin A1C has been adopted as a diagnostic criterion by many, it is not reliable as the sole diabetes screening method during the first year after transplant. Risk factors for PTDM include many of the immunosuppressant medications themselves as well as those for type 2 diabetes. The provider managing diabetes and associated dyslipidemia and hypertension after transplant must be careful of the greater risk for drug-drug interactions and infections with immunosuppressant medications. Treatment goals and therapies must consider the greater risk for fluctuating and reduced kidney function, which can cause hypoglycemia. Research is actively focused on strategies to prevent PTDM, but until strategies are found, it is imperative that immunosuppression regimens are chosen based on their evidence to prolong graft survival, not to avoid PTDM.

PURPOSE: The aim of the study was to investigate the incidence of contrast medium-induced nephropathy (CIN) and risk factors for CIN following endovascular abdominal aortic aneurysm repair or thoracic endovascular aortic aneurysm repair. MATERIALS AND METHODS: After exclusion criteria, 139 (121 males, 18 females) patients aged 20-86 (median 65.5) years who underwent endovascular aortic aneurysm repair between January 2002 and September 2013 were included in this retrospective study. CIN, with ≥25% increase in serum creatinine levels within 3 days after contrast medium administration, was compared to the patients' demographics, risk factors, type and complexity of the endovascular operation, parameters regarding to the contrast medium, preoperative estimated glomerular filtration rate (eGFR), and preoperative and early postoperative serum parameters. Statistical analyses were performed with Kolmogorov-Smirnov, χ (2) and Student's t tests. RESULTS: CIN, detected in 39 of 139 patients (28%), was correlated with preoperative eGFR <60 ml/min/1.73 m(2) (P = 0.04) and high preoperative and postoperative serum urea and creatinine levels. Postoperative serum urea levels (P < 0.001) were significant in multivariate analysis. CONCLUSION: In patients undergoing endovascular aortic aneurysm repair, CIN was correlated with preoperative and postoperative renal impairment, while it was not correlated with the contrast medium dose.

BACKGROUND: Postoperative opioid-induced respiratory depression (RD) is a significant cause of death and brain damage in the perioperative period. The authors examined anesthesia closed malpractice claims associated with RD to determine whether patterns of injuries could guide preventative strategies. METHODS: From the Anesthesia Closed Claims Project database of 9,799 claims, three authors reviewed 357 acute pain claims that occurred between 1990 and 2009 for the likelihood of RD using literature-based criteria. Previously cited patient risk factors for RD, clinical management, nursing assessments, and timing of events were abstracted from claim narratives to identify recurrent patterns. RESULTS: RD was judged as possible, probable, or definite in 92 claims (κ = 0.690) of which 77% resulted in severe brain damage or death. The vast majority of RD events (88%) occurred within 24 h of surgery, and 97% were judged as preventable with better monitoring and response. Contributing and potentially actionable factors included multiple prescribers (33%), concurrent administration of nonopioid sedating medications (34%), and inadequate nursing assessments or response (31%). The time between the last nursing check and the discovery of a patient with RD was within 2 h in 42% and within 15 min in 16% of claims. Somnolence was noted in 62% of patients before the event. CONCLUSIONS: This claims review supports a growing consensus that opioid-related adverse events are multifactorial and potentially preventable with improvements in assessment of sedation level, monitoring of oxygenation and ventilation, and early response and intervention, particularly within the first 24 h postoperatively.

BACKGROUND: The purpose of this study was to determine the incidence and management strategies for post-transplant leukopenia/neutropenia in kidney recipients receiving alemtuzumab induction during the first year following transplantation. METHODS: We prospectively identified 233 adult patients who underwent kidney transplantation with alemtuzumab induction at a single institution. The incidence and severity of leukopenia (white blood cell count [WBC] ≤2500/mm(3)) and neutropenia (absolute neutrophil count [ANC] ≤500/mm(3)) were evaluated at 1, 3, 6, and 12 months post-transplantation. We determined any association with cytomegalovirus (CMV) infection, graft rejection, and infections requiring hospitalization. We also reviewed interventions performed, including medication adjustments, treatment with granulocyte stimulating factor, and hospitalization. RESULTS: The combined incidence of either leukopenia or neutropenia was 47.5% (n = 114/233) with an average WBC nadir of 1700 ± 50/mm(3) at 131.0 ± 8.5 days and an average ANC nadir of 1500 ± 100/mm(3) at 130.4 ± 9.6 days. No significant difference in graft rejection, CMV infection, or infections requiring hospitalization was found in the leukopenia/neutropenia group vs the normal WBC group (P = .3). The most common intervention performed for leukopenia/neutropenia group was prophylactic medication adjustment. Six patients (5.2%) required a change in >1 medication. The majority of these patients also required granulocyte stimulating factor (61.5%; 32/52), with an average of 2.5 doses given. A total of 25 patients (21.9%) required hospitalization due to leukopenia/neutropenia with an average length of stay of 6 days. CONCLUSIONS: Kidney transplant patients receiving alemtuzumab induction required significant interventions due to leukopenia/neutropenia in the first year post-transplantation. These results suggest the need for additional studies aimed at defining the optimum management strategies of leukopenia/neutropenia in this population.

OBJECTIVE: To report the outcomes of an institutional protocol for periprocedural anticoagulant (AC) management in children with acute lymphoblastic leukemia (ALL). STUDY DESIGN: Children being treated for ALL who received full-dose (therapeutic) anticoagulation before undergoing at least 1 lumbar puncture (LP) were included in this retrospective cohort study. The main outcome was the risk of traumatic LP; exploratory analysis included the risks of symptomatic spinal hematoma and progression/recurrence of the thrombotic event. Analyses were conducted using logistic regression analysis with a generalized estimating equation approach. RESULTS: Twenty-two children with ALL receiving an AC underwent a total of 396 LPs. Although traumatic LP was associated with full-dose AC therapy in univariable analysis, a multiple logistic regression model controlling for other risk factors for traumatic LP showed that AC therapy was not significantly associated with the risk of traumatic LP when the ACs were held as per the institutional protocol. No patient developed symptomatic spinal hematoma. Exploratory analysis revealed that AC dose, a likely marker of thrombus burden, was significantly associated with progression/recurrence of the thrombotic event in univariable analysis. CONCLUSION: In our cohort, recent AC therapy was not statistically associated with an increased risk of bleeding after LP when following a specific protocol for periprocedural AC management. The risk associated with the progression/recurrence of thromboembolic events requires further evaluation.

BACKGROUND: Phenylephrine eye drops are widely used as mydriatic agent to reach the posterior segment of the eye. In literature, many reports suggest a systemic absorption of this agent as a source of severe adverse drug reactions. Hence, we reviewed our experience with topical phenylephrine in ophthalmic surgery. METHODS: In May 2006, following US guidelines publication, a standard operating procedure was issued in our operating rooms to standardize the use of phenylephrine eye drops in our practice. Two years later, after the occurrence of a cluster of serious adverse drug reactions in infants undergoing surgery, a review of phenylephrine safety and systemic complications incidence was performed. RESULTS: We observed 451 pediatric patients, and 187 met the inclusions criteria: Among them, 4 experienced hemodynamic complications due to phenylephrine eye drops. The incidence of major complications was 2.1%. CONCLUSIONS: Two different patterns of side effects occurred. The first one was a cardiovascular derangement with severe hypertension and heart rate alterations; the other one involved exclusively pulmonary circuit causing early edema. These clinical manifestations, their duration, and treatment responses are all explainable by alfa1-adrenergic action of phenylephrine. This hypothetic pathogenesis has been confirmed also by the usefulness of direct vasodilators (anesthetic agents) and by the negative outcome occurred in the past with the use of beta-blockers.
