Modified Nasal Spray Shows Promise in Reducing Anxiety and Pain for Medical Procedures
A groundbreaking prospective study conducted at a hospital in Mumbai has revealed that a modified intranasal spray could significantly alleviate anxiety and pain in adults undergoing specific medical procedures. The research, which focused on gastrointestinal endoscopy, highlights a potential shift in pre-operative sedation methods away from traditional intravenous (IV) drips.
Study Details and Methodology
The study, carried out from July 2023 to June 2024 and recently published in the International Journal of Clinical Anesthesia and Research, involved over 300 adults scheduled for gastrointestinal endoscopy at H N Reliance Hospital in Girgaum, Mumbai. Participants were divided into two groups: a control group that received standard sedation via an IV drip and a test group that was administered pre-operative medications through the intranasal spray.
The spray contained a combination of medications commonly used by anaesthetists, including ketamine, midazolam, and lignocaine. These drugs are typically employed to sedate patients and manage pain associated with surgical interventions.
Key Findings and Benefits
According to the study authors, the intranasal drug delivery system demonstrated superior outcomes compared to the intravenous procedural sedation group. Dr. Misha Mehta, one of the authors, stated, "The intranasal drug delivery system achieved better pain control, mobility, and lower post-operative anxiety versus the intravenous procedural sedation group."
Senior author and anaesthesiologist Dr. Hemant Mehta elaborated on the psychological benefits, noting, "When patients are brought to the operation theatre, they are anxious—for the first time, they are away from their family and they are also worried about the instruments in the OT. This spray puts them in a trance-like sleep from which they can awaken when spoken to."
The doctors further explained that the nasal spray helped eliminate the fear associated with IV medications, and patients reported fewer post-operative symptoms such as vomiting. The spray was administered before surgery and at four-hour intervals, contributing to a more comfortable recovery process.
Context and Expert Insights
This development aligns with broader trends in anaesthesia technology. An article in Anesthesiology and Perioperative Science from January 2025 highlighted, "The rapid advancement of AI has facilitated the emergence of automated anaesthesia systems, significantly enhancing the precision, efficiency, and adaptability of anaesthesia management in complex surgical environments." The intranasal anaesthetic spray represents a step in this direction, offering a more patient-friendly approach.
However, experts caution that while such sprays could be beneficial for anxiety reduction, they may not suffice for all sedation needs. Additional professor Dr. Ashish Mali from BMC-run Nair Hospital in Mumbai commented, "Sedation dosages depend on the kind of surgery being performed." He pointed out that pre-operative IV drugs are often preferred in cases where a patient's blood pressure drops during surgery, as they allow doctors quick access to blood vessels.
Dr. Mali also noted limitations, stating, "Also, nasal sprays, while convenient, may not be suitable for all patients. It may be useful for dentistry, in paediatric patients, and certain non-invasive procedures like a long MRI scan or endoscopy." This suggests that the spray's application might be more targeted rather than a universal replacement for IV sedation.
Implications and Future Directions
The study's findings could pave the way for enhanced patient comfort in medical settings, particularly for procedures that induce significant anxiety. By providing a non-invasive alternative to IV sedation, the intranasal spray has the potential to improve patient experiences and outcomes in specific contexts.
As research continues, further investigations may explore the spray's efficacy across a wider range of medical procedures and patient demographics, potentially integrating with AI-driven anaesthesia systems for optimized care.
