Perioperative Considerations for Antithrombotic Therapy in Oculofacial Surgery: A Review of Current Evidence and Practice Guidelines

Pain control and subconjunctival haemorrhage after intravitreal injection using cooled anaesthetic eyedrops and antiseptics: A prospective, double-blind, randomized controlled trial

PURPOSE

To evaluate whether cooled anaesthetic eyedrops and antiseptics alleviate pain and minimise subconjunctival haemorrhage following intravitreal injection.

METHODS

A prospective, double-masked, randomised controlled trial of 100 participants receiving either cooled (n = 50) or room temperature (n = 50) topical anaesthetic eyedrops and antiseptics before receiving an injection of bevacizumab. Baseline tolerability was estimated using a self-reported pain sensitivity questionnaire.

RESULTS

Overall tolerability was comparable between the study group and the control group (0.75 ± 0.13 vs. 0.74 ± 0.14, respectively, p = 0.99). Subconjunctival haemorrhage incidence was similar in both groups (80% vs. 86%, respectively, p = 0.113), as was subconjunctival haemorrhage size (2.75 ± 5.51 mm2 vs. 5.53 ± 10.72 mm2 , respectively, p = 0.11). Sub-group analysis demonstrated that the participants taking daily ocular eyedrops who received cooled anaesthetic eyedrops and antiseptics reported less pain at 10 min and less burning sensation at 24 h compared with matched controls (0.67 ± 1.50 vs. 2.50 ± 3.03, respectively, p = 0.040 and 0.00 ± 0.00 vs. 1.44 ± 2.96, respectively, p = 0.045). Participants who received cooled eyedrops and did not use antithrombotic therapy had smaller-sized subconjunctival haemorrhages compared with matched controls (1.55 ± 1.87 mm2 vs. 8.29 ± 14.61 mm2 , respectively, p = 0.038). Participants with hypertension who received cooled eyedrops had smaller-sized subconjunctival haemorrhage compared with matched controls (2.33 ± 4.99 mm2 vs. 6.89 ± 12.41 mm2 , respectively, p = 0.045).

CONCLUSION

The benefit of using cooled anaesthetic eyedrops and antiseptics to alleviate pain and minimise subconjunctival haemorrhage following intravitreal injection was not proven in the general population. It may be beneficial in part for some patients, such as those who regularly use eyedrops, patients with hypertension or those not on antithrombotic therapy.

Patient's Perceptions of Importance of Discontinuing Antithrombotic Medication Before Oculoplastics Surgery

This study aims to analyze patients' perspectives to ultimately gain insight into the patients understanding in 3 broad categories: their understanding of how their medications, supplements, and over-the-counter drugs work, their understanding of the risks these agents pose in a surgical setting, and their preferences for the continued use of the agents during and after oculoplastic surgery. To obtain these data, the authors prospectively surveyed 129 patients who had an oculoplastic surgery clinical evaluation at our tertiary care academic facility. Because no previously validated questionnaire on this topic existed, the authors utilized a novel questionnaire the authors developed. For antithrombotic medications, about 60% of patients felt there were risks associated both with stopping and continuing the agent during surgery. For antithrombotic supplements, more patients answered there were risks associated with continuing the agents during surgery versus stopping the agents during surgery (40% versus 25%, respectively). There was a relationship between patients' knowledge that they were on an antithrombotic prescription and their understanding of the risks associated with antithrombotic usage during surgery as well as sudden discontinuation of the prescription. With an understanding of the patient's point of view, surgeons will be equipped to have multifaceted conversations with their patients surrounding their medications, systemic health, and oculoplastic surgery.

Upper Blepharoplasty: An Evidence-Based Assessment of Preoperative Considerations and Surgical Techniques

Upper blepharoplasty is one of the most common facial plastic surgical procedures performed. Due to its growing popularity, an abundance of articles is available describing variations in the surgical technique and outcomes. As a result, it has become increasingly difficult to identify appropriate surgical literature validated by a high level of evidence. The purpose of this review is to identify and describe specific evidence-based components of the preoperative evaluation and surgical approach in upper blepharoplasty surgery.

Perioperative Medication Management in Elective Plastic Surgery Procedures

BACKGROUND

Perioperative medication management is vital to maintain patient safety while under anesthesia, as well as to avoid postoperative complications. Plastic surgeons make daily decisions on whether to ask a patient to stop taking medication before their surgery. These important decisions can affect bleeding risk, wound healing, and interactions with anesthetics, which can range from minor to life-threatening. Current plastic surgery literature lacks a comprehensive review of perioperative medication management, with existing reports focusing on specific procedures and specific medication classes.

METHODS

A PubMed database search was conducted for articles through July 2021. The bibliographies of included studies were also examined for articles not acquired in the initial search queries. The authors included studies on medication usage and perioperative guidance in patients undergoing elective plastic surgery procedures. The authors excluded studies unrelated to plastic surgery and studies where the medications were used as an intervention. Abstracts, animal studies, studies involving the pediatric population, and book chapters were also excluded, as well as articles not published in English.

RESULTS

A total of 801 papers were identified by our search terms. After title and abstract screening, 35 papers were selected for full-text review. After full-text review, 20 papers were selected for inclusion, with an additional 6 papers from cited references added. Of the 26 papers, 6 papers discussed psychotropic drugs, 6 papers discussed medications affecting hemostasis, 4 papers discussed hormone-containing medications, 3 papers discussed antilipid medications, 2 papers discussed antihypertensive medications, 2 papers discussed herbal supplements, 1 paper discussed both psychotropic and herbal supplements, 1 paper discussed medications affecting wound healing, and 1 paper discussed rheumatologic medications. A summary of those recommendations was then compiled together.

CONCLUSIONS

The perioperative medication management in elective plastic surgery procedures remains a complex and multidisciplinary process. It is important to manage these patients in a case-by-case manner and to consult a specialist when necessary. Careful medication reconciliation is essential to decrease the likelihood of adverse outcomes and interactions with perioperative anesthetics.

Intraoperative hemostatic agents in orbital surgery

PURPOSE

While preoperative optimization and post-operative management of hemorrhagic complications are increasingly clear, intraoperative control of bleeding during orbital surgery has received less attention. Thanks to advances in other fields, new technologies may be employed during these interventions. This review was designed to discuss these modalities.

METHODS

A literature search was performed to identify manuscripts that are related to the management of intraoperative bleeding. The bibliographies of these studies were also assessed to identify additional references. Data was abstracted from these studies.

RESULTS

Multiple hemostatic agents are currently used in orbital surgery, and related surgical fields have carefully assessed these interventions. Direct mechanical, flowable, and pro-thrombotic medications may all play key roles in achieving hemostasis.

CONCLUSIONS

Orbital surgeons have several potential technologies to facilitate hemostasis, and the armamentarium continues to grow. Future investigations will yield more targeted medications that may be delivered in novel manners to enhance the intraoperative experience.
