Anaesthetic considerations of the HIV-infected patients

Surgical pathway for HIV‑infected patients based on the ERAS strategy (Review)

Enhanced recovery after surgery (ERAS), which is based on evidence-based medicine, focuses on patients and aims to reduce the psychological and physiological trauma stress reactions and complications of patients, thus shortening the duration of hospitalization, promoting rapid recovery and reducing medical expenses, readmission rate and mortality rates. Acquired immunodeficiency syndrome (AIDS) is caused by human immunodeficiency virus (HIV) infection. Patients with HIV/AIDS, as with other patient populations, can suffer from several surgical-related diseases. Therefore, the need for surgery in this group of patients exists and the surgical services required by patients with AIDS has gradually become an urgent matter of concern. According to relevant literature and the authors' clinical experience, the present review summarizes the current surgical approaches for patients infected with HIV based on ERAS. In the present review, the related issues observed at different stages of surgery, including pre-operative, intra-operative, post-operative and follow-up stages, are discussed.

Patients with immunodeficiency

Patients presenting in an immunocompromised state merit special consideration when being evaluated for fitness to undergo surgery. A variety of immunodeficient conditions and their respective therapies, including human immunodeficiency virus, cancer, and transplantation, exert numerous systemic effects that may lead to multiorgan dysfunction. Understanding the potential impact of these disease manifestations, and their proper evaluation, is essential in achieving optimal perioperative outcomes for these patients.

The potential anesthetic threats, challenges and intensive care considerations in patients with HIV infection

Acquired immunodeficiency syndrome (AIDS) has become a pandemic with ever looming danger of its transmission in health professionals. The number of AIDS patients has increased tremendously over the last two decades, who present for surgical procedures as well as who get admitted in intensive care unit for their critical condition. As such anesthesiologists and intensivists are exposed to potential risk of disease transmission on a daily basis from such patients. The guidelines and protocols formulated in the western world regarding prevention of disease transmission cannot be applied uniformly in the developing nations, such as India due to various factors and limitations. As such there is a continuous need felt in this arena to prevent the catastrophic consequences of AIDS in our medical fraternity while treating such patients in operation theatres and critical care units. This study reviews the various pathophysiological aspects, anesthetic considerations, intensive care implications, and various areas where current knowledge about AIDS can be applied to prevent its potential transmission in high-risk clinical groups.

Preoperative assesment of the immunocompromised patient

In some surgical patients immunosuppression is easily apparent and directly caused by known underlying disease or treatment. In others, although induced by the underlying disease, immunosuppression may be less obvious. Perioperative management of immunocompromised patient is mostly directed by the fact that immunosuppression itself does not cause pathology, but does leave the patient prone to infection. Immunodeficiency can be broadly characterized as congenital (primary) or acquired (secondary). The majority of immune deficiencies that are of interest to the anaesthetist are acquired. They can be present both in children and adults, in a huge variety of patients that are presented preoperatively. Most of them do not require different than usual perioperative anaesthetic management. However, in some of them specific aspects of treatment should be considered, such as HIV infected, cancer, transplant patients, and those scheduled for organ transplantation.
