Perioperative Considerations for Person-Centered Gender-Affirming Surgery.

With more than 1 million people identifying as transgender in the United States alone, the likelihood of encountering a transgender patient and their family of choice in the perioperative setting is very high. A lack of data exists to equitably inform transgender-specific issues, as well as the associated morbidity during the transgender reassignment perioperative period. Anaesthesiologists should actively acquire the knowledge and skills needed to inclusively and respectfully manage these patients and be aware of their unique physiological and psychosocial needs. The pre-operative approach includes a detailed history, focusing on the patients cross-sex hormone treatment (CSHT) regimen and associated medical conditions. An in-depth understanding of commonly used hormones such as estrogen and testosterone and their effect in the perioperative periods is essential. The physical examination should be relevant to the anatomy that is currently present while taking into consideration feminising and masculinising procedures (e.g., genioplasty, thyroid cartilage augmentation), how these interventions alter the anatomy, and potential airway complications. Laboratory results should be interpreted with care – and with expert assistance if needed - as hormone therapy might affect reference values. In addition, risk assessment tools should be used with caution since they often include sex in their scoring system but do not account for the use of CSHT. Intraoperative considerations include urethral catheter placement, drug dosing, and drug interactions that are commonly encountered in the transgender patient. Special attention should be taken in transgender females who have undergone vocal feminization, as case reports have described unexpected difficult airway management. A multimodal approach, which includes regional blocks and attention to pre-existing chronic pain conditions, should be employed as part of the post-operative pain management plan. The post-operative nausea and vomiting risk has not yet been established in this population, requiring appropriate anti-emetic prophylaxis. Despite societal advances that improve transgender health, the medical community still lacks empirical evidence to effectively mitigate the distinctive challenges confronted by this at-risk population.
