Some Aspects of Sleep Disturbance in Coronary Patients

Abstract

Of 42 coronary care patients studied during 10 hr. of polygraphically recorded sleep, 28 were in an open-ward coronary care unit and 14 were in a semi-private telemetry unit. The observed sleep disturbances were not a function of type of unit, length of hospitalization, sex, or medications. Sleep was significantly less fragmented in those patients judged less severe in pathology. These results indicate that alterations in normal sleep patterns occur routinely within coronary care environments, even in the absence of disturbing environmental stimuli and suggest that a closer analysis be made of sleep in these settings in light of the known relationships between sleep and cardiac function.

Sleep in Hypercapnic Critical Care Patients Under Noninvasive Ventilation

“…There were no differences between groups, including the time under NIV previous to the study inclusion (19 hrs [17][18][19][20][21] in the NIV D group vs. 13 hrs [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] in the NIV ICU group; p = 0.41). The only difference was a higher Epworth sleepiness score in the NIV D group than in the NIV ICU group (14 [10][11][12][13][14][15][16][17][18][19][20][21] vs. 5 [2][3][4][5][6][7][8][9]; p = 0.01). The reasons for NIV treatment were acute on chronic respiratory failure (n = 16), cardiogenic pulmonary edema (n = 3), pneumonia (n = 2), and postextubation respiratory failure (n = 3).…”

“…A high sleep fragmentation with a marked reduction in the duration of rapid eye movement (REM) and slow wave sleep (SWS) has been described (1,3,4). Multiple factors contribute to these abnormalities such as the severity of illness (5), medications (6), noise (2,3), patient care activities, (3) and mechanical ventilation (4,(7)(8)(9). The ventilatory mode (4,7,8), ventilatory settings (8,9), and patientventilator synchronization (7,9,10) can have an impact on sleep quality.…”

Sleep in the surgical intensive care unit: continuous polygraphic recording of sleep in nine patients receiving postoperative care.

“…Mean values of sleep time in various sleep stages (minutes per sleep period)Sleep period I denotes period from start of recording until 8 am next morning(8)(9)(10)(11)(12)(13)(14)(15)(16) hours of recording). Sleep periods II, III, and IV denote following 24 hour periods from 8 am to 8 am including second, third, and fourth postoperative nights respectively.…”

Development and Validation of Sleep Disturbance Questionnaire in Patients with Acute Coronary Syndrome

“…ACS causes sleep disturbance in patients. Some studies reported that pain and the chronic nature of the disease in patients hospitalized in CCU cause disorders in sleep pattern [ 14 , 43 , 45 , 47 – 51 ].…”
