Market Dynamics:

Drivers

• Improvement in Anesthesia Delivery Systems is Driving the Market Growth

The global inhalation anesthesia market is largely propelled due to technological advancements in anesthesia delivery systems. Contemporary engines are now equipped with vaporisers controlled digitally and closed-circuit systems, which permit the accurate measurement and control of volatile agents such as sevoflurane and desflurane. These advancements help ensure patient safety by sustaining accurate concentrations of anesthetic and reducing the likelihood of human error. Premium systems also allow for low-flow anesthesia techniques in order to conserve agents and save costs. Perioperative care is further facilitated by linkage to electronic health records (EHR) and real-time patient monitoring. While hospitals seek innovative solutions that balance efficiency, performance, and safety, the use of these advanced anesthesia machines continues to rise, leading to an increase in demand for inhalation anesthetics suitable for use in such systems.

In January 2025, a new GE Healthcare compact anesthesia machine, the Carestation 600 series V2, was introduced, emphasising its use in limited operating space, showcasing continued development of delivery technology.

• The Growing Adoption of Inhalation Induction in Pediatrics and Geriatrics is Boosting the Market

Due to its non-invasive and well-tolerated administration, inhalation anaesthesia is favoured even for the induction of anaesthesia in paediatric and aged patients. Furthermore, rather than an IV induction that can be painful, or difficult to achieve in small children or patients with frail veins, inhalational agents such as sevoflurane provide a calm, comfortable mask induction. Sevoflurane is especially preferred for its pleasant smell and low airway irritability as well as rapid onset without excitation. In the geriatric population, when inhalation induction is used, there are fewer complications related to IV access and drug metabolism, because of the inhalation agents’ lack of systemic effect. This clinical flexibility renders inhalation induction a safer and more useful alternative, which may increase its application in these vulnerable patient populations.

Restraint

• Side Effects and Safety Concerns are Hampering the Market Growth

A major restriction on the inhalation anesthesia market trends is the possibility of side effects of volatile anesthetic agents. Conventional inhaled drugs such as sevoflurane, isoflurane, and desflurane can irritate the airway, especially during induction, and can lead to coughing, laryngospasm, or breath-holding, especially when used in young children or in sensitive adult patients. A small number of agents can also cause malignant hyperthermia, a lethal phenomenon in genetically predisposed individuals.

Furthermore, chronic work exposure to trace anesthetic gases in operating rooms with ineffective scavenging may adversely affect the health of anesthesia providers, such as cognitive impairment and reproductive dysfunction. Integrating these observations, there has been a reinforcement in clinical practice toward a guarded approach, and more regulation has been enforced. In addition to organ toxicity (e.g., nephrotoxicity with prolonged sevoflurane in high doses), agents need to be selected and monitored with care, thus complicating anesthetic management and impairing adoption in low-risk or resource-poor settings.

Segmentation Analysis:

By Drug

The sevoflurane segment dominated the inhalation anesthesia market share of 40.6% in 2024, primarily due to the advantages offered, such as rapid induction and recovery, low pungency, and high safety margin, making it the preferred choice for both adult and pediatric surgeries. Its compatibility with low flow techniques fulfills economic and ecological objectives, even more in developed areas (e.g., North America and Europe). In addition, sevoflurane is favored by hospital protocols and preferences among anesthesiologists, which strengthens its foothold in the market.

The desflurane segment is expected to register the highest CAGR over the forecast period as ultra-fast onset and emergence help in ambulatory and outpatient surgery settings. With the current medical trend toward shorter hospital stays and with more day-care surgery, the pharmacokinetic properties of desflurane are more and more interesting. Furthermore, ongoing developments aimed at minimising its ecological impact (including the introduction of scavenging systems and upgrades to vapourisers) should help drive its uptake in high-volume surgical centers, including in anesthesia modernization areas.

By Application

The maintenance segment dominated the inhalation anesthesia market in 2024 with a 68.2% market share. The various drugs used in inhalation anesthesia are mainly used to maintain anesthesia during surgeries. At the end of induction, typically using IV agents, volatile anesthetics (eg, sevoflurane, isoflurane) are administered via vaporizers on the tissue until the end of anesthesia. The extended maintenance period versus the induction, in combination with the high use of agents in this phase, makes it the most economically impactful course of action. Hospitals also favour inhalational maintenance due to it is more adjustable and controllable for anesthetic depth.

The induction segment is anticipated to grow at the highest CAGR during the forecast period due to the preference for inhalation induction is growing, particularly among pediatric and geriatric patients in whom venous access can be difficult. Sevoflurane, especially, is becoming increasingly popular for its non-irritating nature and pleasant mask induction, which is suitable in children and for ambulatory surgery. Moreover, the growing preference for minimally invasive and day care surgeries is favorable to inhaled agents for induction and maintenance, thereby driving the demand for inhalation-based induction techniques.

By Patient Type

The adult segment held the largest share of the inhalation anesthesia market in 2024 due to the high incidence of the large number of surgical procedures being performed on the adult population, such as orthopedic, cardiovascular, and general surgeries, which is driving the growth of this market segment. The adult population is the predominant patient group for both elective and emergency surgery, leading to considerable demand for maintenance and induction anesthesia. Most clinical protocols and anesthesia machines are also designed for use in adults, and hospitals in both developed and developing countries emphasise adult surgical care due to its higher prevalence and wider range.

The pediatric segment is projected to grow at a significant rate during the forecast period as global awareness and access to pediatric surgical care increase. Inhaled anesthesia, especially with an agent such as sevoflurane, is a commonly favored technique in pediatric patients, as it is non-irritating, quick-acting, and conducive to mask induction without the pain associated with IV access. Increasing prevalence of pediatric hospitals, neonatal surgical programs, and government initiatives for child health are also driving the adoption of inhalation anesthesia among the pediatric age group.

By End Use

The hospital segment accounted for the largest share of the inhalation anesthesia market in 2024, with a 66.34%. Due to the high volume of complex and high-risk surgeries performed in hospitals, the need for continuous monitoring and an advanced level of anesthesia management is the major factor responsible for the dominance of this end-user segment. General hospitals have state-of-the-art anesthesia workstations, anesthetists, and the presence of recovery units; for this reason, inhalation agents such as sevoflurane and isoflurane are widely used in hospitals.

The Ambulatory Surgical Centers (ASCs) segment is anticipated to exhibit the fastest growth over the forecast years as a result of the growing global trend toward outpatient and day surgeries. ASCS can take advantage of cheaper overheads, shorter patient turnaround times, and higher procedural throughput, well-served by rapidly-acting inhaled agents such as desflurane and sevoflurane. With healthcare systems pushing to lower hospitalization costs and increase efficiency, the uptake of inhaled anesthesia in ASCs is anticipated to witness promising growth, particularly in developed regions and metropolitan cities.
