Brief Summary

Neurosurgical interventions are a leading cause of death and disability in adults, and managing intracranial hypertension in the acute phase is a critical treatment process to prevent secondary brain injury . Among surgical and medical interventions to control intracranial pressure, appropriate sedoanalgesia protocols can provide comfort to patients and directly control intracranial pressure by regulating cerebral metabolism . Appropriate sedoanalgesia has been reported in the literature to reduce cerebral metabolic rate, cerebral blood flow, and cerebral blood volume by resting the brain, and has been observed to improve elevated intracranial pressure. Resting the brain means a decrease in cerebral metabolic rate, allowing it to utilize energy more efficiently . This decrease in the brain's need for blood supply decreases, thereby decreasing cerebral blood flow. This reduction in blood flow can help reduce intracranial pressure, as excessive blood flow and fluid accumulation can lead to elevated intracranial pressure. In this regard, sedoanalgesia applications help patients become more stable and better maintain cerebral perfusion pressure . This can help preserve brain function by ensuring adequate oxygen and nutrients to brain tissue . In this context, sedoanalgesia is an important tool in managing intracranial pressure and can be used strategically to improve brain health.

However, inadequate sedoanalgesia may fail to achieve intended treatment goals, while excessive sedoanalgesia can lead to complications associated with lethal sedation. Therefore, it is important to determine the appropriate sedoanalgesia protocol and continuously monitor patient outcomes (such as vital signs, blood gas parameters, pain, sedation scores, and GCS).

As healthcare professionals, nurses, along with physicians, are the decision-makers and implementers in the sedoanalgesia management of critically ill patients in intensive care, ensuring optimal sedoanalgesia, achieving the desired level of sedoanalgesia, optimizing patient comfort, ensuring patient safety, and maintaining sedoanalgesia when indicated. Therefore, our study was designed to evaluate the impact of the sedoanalgesia protocol applied to intensive care patients, including neurosurgical patients, on patient outcomes and is believed to guide the literature.

Detailed Description

The study is planned as a randomized controlled intervention study to evaluate the effect of the sedo-analgesia protocol applied to intensive care patients on patient outcomes.

Conditions

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: SUPPORTIVE_CARE
• Blinding Strategy: SINGLE

Study Groups

Control Group

The control group will receive the clinic's routine sedation-analgesia management plan. Patients will be monitored and their vital signs will be recorded upon admission to the intensive care unit. Medications will be administered according to the physician's orders based on improved treatment and analgesia. The nurse responsible for the patient will administer sedatives based on their own observation/assessment and the physician's order, without any sedation-analgesia protocol. The nurse responsible for the patient will also record all treatments as directed by the physician. During follow-up, data collection tools (RASS, HSF, NVPS, and CPOT) will be used to record patients' pain, anxiety, sedation level, GCS, blood gases, and vital signs twice daily, taking into account non-busy family visits and nursing care hours, between 10:00 and 11:00 and 14:00 and 15:00 (before, during, and 30 minutes after).

Group Type: OTHER

control group

Intervention Type: OTHER

The clinic's routine sedation analgesia management plan will be implemented.

Experimental Group

The experimental group will receive an algorithmic sedoanalgesia protocol led by a nurse, and alarm volume will be adjusted in accordance with WHO recommendations. To ensure the patient understands the concept of daytime, the brightness of the lights in the patient's room will be adjusted only after 10:00 PM, ensuring they do not disrupt treatment and care. The patient's primary nurse will then assess the RASS, NVPS, and CPOT for three days. Based on these assessments, the patient will adjust the medication infusion rate and strive to achieve the target scale value range. During follow-up, the researcher will play music twice daily, between 10:00 AM and 11:00 AM and 2:00 PM and 3:00 PM, taking into account non-busy family visits and nursing care hours. Music will be played using pre-recorded music from selected Musi Cure albums for three days. Music will be played for 30 minutes at 10:00 AM and 2:00 PM. Data will be recorded using data collection tools.
