Effect of Stress Ball Use on Pain, Sleep Quality and Physiological Parameters

Intensive care units (ICU) are environments where critically ill patients are treated and require advanced medical intervention . Critically ill patients in ICU are monitored from the time of admission and their physiological parameters such as blood pressure, heart rate, respiratory rate, oxygen saturation are closely monitored. In addition to the existing diseases of patients in intensive care units, the presence of many technological devices such as haemodynamic monitoring required for follow-up and treatment and the complex nature of intensive care services often cause patients to experience pain .

More than 50% of intensive care patients experience pain due to surgical intervention, invasive procedures and morbidity. It is reported that patients experience 30% pain during rest and 50% pain during routine nursing practices such as endotracheal aspiration, deep breathing and coughing exercises, positioning, wound care, and catheter placement due to health problems. However, it is seen that pain management is generally inadequate and this situation affects the physical and psychological recovery processes of patients. The whole organism can be affected by pain, and accordingly, physiological and behavioural symptoms may occur in individuals experiencing pain. After the neuroendocrine response to pain, heart rate, cardiac output, myocardial oxygen consumption and peripheral vascular resistance increase as physiological symptoms.

In intensive care units where critically ill patients are followed up, changes in physiological parameters due to pain and other factors can be life-threatening. Defining pain, evaluating physiological parameter changes, and reducing or eliminating pain with the right nursing interventions is an important responsibility for nurses in specialised units such as intensive care. However, due to the critical condition of patients in the intensive care unit, patients may not be able to express pain subjectively and nurses may be inadequate in pain assessment. Generally, pain management is performed according to the physician's order, and appropriate nursing diagnoses cannot be made due to inadequate knowledge of nurses about pain. Inadequate pain treatment causes sleep deprivation, which is frequently seen in intensive care patients.

In intensive care units, many factors other than pain (e.g., constantly bright environment in intensive care, medical devices and sounds made by medical devices, IV drug treatments, lack of attention to privacy, too cold or hot environment and mechanical ventilation, etc.) can cause sleep problems by causing excessive stimulation. Sleep is a critical part of the healing process; however, ICU patients often do not get enough sleep. In addition to its negative effects on the immune system, sleep deprivation may also impair the general well-being of patients and prolong their recovery time. Therefore, improving sleep quality in ICU can accelerate the treatment process of patients and increase their general well-being. Intervening in environmental factors, for example, reducing the lights in the environment and muting or switching off the sound of vital medical devices, carries a great risk. For this reason, it may be easier to change patients' perception of the environment rather than changing the environment. It is especially recommended to use non-pharmacological methods to reduce the perception of the environment.

Although pharmacological treatment options are available for the management of these psychological and physiological burdens in intensive care patients, in recent years, non-pharmacological methods have increasingly found a place in the care of intensive care patients. One of these methods is the use of a stress ball. The stress ball, which is a low-cost and easily applicable method, can provide physical relief to patients. The stress ball suppresses most of the nerves and muscles around the wrist and hand, which are directly connected to the brain, and stimulates the nerves and muscles. This mechanism reduces the release of stress hormones and regulates blood pressure by providing relaxation and relaxation. Stress ball, which is easy to apply, inexpensive, has no side effects on the patient, and is an effective method in physical and emotional recovery, is an intervention that can be preferred in nursing practices. Stress ball application is effective on pain, anxiety and vital signs in different patient groups, but no randomised controlled study has been found in which stress ball application was performed in intensive care patients. In this study, it was aimed to examine the effect of stress ball use on pain, sleep quality and physiological parameters in intensive care patients.
