Association of Intravitreal Injections With Blood Pressure Increase: The Following Excitement and Anxiety Response Under Intravitreal Injection Study.

ABSTRACT:

Importance

Despite the unquestionable effectiveness of anti-vascular endothelial growth factor therapy (VEGF), there is ongoing controversy about potential systemic adverse effects. Besides the direct adverse effects of anti-VEGF agents, other factors associated with the injection itself, such as perioperative blood pressure fluctuations, may contribute to adverse events.

Objective

To determine blood pressure fluctuations during intravitreal injections.

Design, setting, and participants

Prospective observational study at a tertiary referral center (Department of Ophthalmology, University Hospital Bern, Bern, Switzerland). Consecutive patients scheduled for intravitreal injections were recruited. Data were analyzed between October 2017 and January 2018.

Main outcomes and measures

Systolic and diastolic blood pressure, pulse rate, and oxygen saturation were recorded before, during, and after the intravitreal injection. An anxiety questionnaire was completed by all participants. Multivariate regression analysis was used to investigate potential factors associated with blood pressure rise during injections.

Results

Two hundred one patients (92 women and 109 men) were included in this study, with a mean age of 68 years (range, 18-93 years). Mean (SD) systolic blood pressure increased from a baseline of 150 (20) mm Hg to 162 (24) mm Hg following the preparation procedure to 168 (24) mm Hg during the injection (P?Conclusions and relevanceThe intravitreal injection process is associated with a transient increase in blood pressure. Most of the increase occurs following the preparation before the injection itself. This may constitute a risk factor for cardiovascular or cerebrovascular complications during treatment and could be of particular relevance in patients at high risk for such events and those receiving frequent injections. Future work may be needed to determine whether, in patients at risk for cardiovascular or cerebrovascular events, perioperative blood pressure monitoring or antihypertensive therapy needs to be considered.

Project description:BACKGROUND:Intravitreal injection (IVI) is a very common vitreoretinal procedure, and multiple injections are often required per patient. This systematic review was conducted to evaluate the effectiveness of various local anesthetic techniques in reducing pain during injection. METHODS:A systematic review was conducted based on searches of Cochrane, LILACS, PubMed, Scopus, Web of Science, and the gray literature (Google Scholar). The end search date was February 19, 2016, across all databases. We classified pain by converting visual analog scale (VAS) scores (0-100 mm) into Jensen's classification levels: 0-4, no pain; 5-44, mild pain; 45-74, moderate pain; and 75-100, severe pain. An intervention was considered clinically significant when pain score change was >12 mm on a 100-mm scale. RESULTS:Eight studies out of 23 met the eligibility criteria. The total number of patients was 847. Most studies (5/8 [62.5%]) were at unclear risk of bias because of unclear randomization, thus providing only moderate evidence to this review. The anesthetic techniques included eye drops with proparacaine, tetracaine or cocaine, a lidocaine pledget or gel, and subconjunctival injection of 2% lidocaine or 0.75% levobupivacaine. No study comprised all of the techniques. Pain was mild (VAS scores, 5-44 mm) regardless of anesthetic technique. A clinically significant intervention (pain score change >12 mm) was found for only one study comparing proparacaine drops, lidocaine gel, and subconjunctival lidocaine; in that study, a subconjunctival injection of 2% lidocaine provided the greatest pain reduction. A meta-analysis was not possible due to study heterogeneity. CONCLUSIONS:Patient pain during IVI under topical anesthesia is mild regardless of anesthetic technique. A subconjunctival injection of 2% lidocaine could be an option for highly sensitive patients. However, with moderate level of evidence, no single anesthetic technique could be defined as the best option for IVI.
