Sleep in the Intensive Care Unit

Análise de estressores para o paciente em Unidade de Terapia Intensiva

“…Diversos estudos têm demonstrado que a privação do sono é um problema comum na UTI e está relacionado a alterações mentais nesses pacientes [15][16][17][18] . A privação do sono em UTI parece ter várias causas, incluindo a doença crôni-ca do paciente, a presença de uma doença aguda sobreposta ou realização de procedimento cirúrgico, as medicações utilizadas e o próprio ambiente da UTI 19,20 . Medidas terapêuticas para melhorar esta condição devem ser direcionadas a todas as potenciais causas, com ênfase na criação de um ambiente favorável que facilite o início do sono, diminua o número de interrupções e possibilite a manutenção do ciclo sono-vigília nesses pacientes 20 .…”

Effect of Ventilatory Variability on Occurrence of Central Apneas

“…Sleep disruption is common in critically ill patients and may influence the clinical course of the acute illness. 8,34,35 Even if it is well documented that sleep abnormalities may impair psychological and physiological well-being, with effects such as increased protein catabolism, decreased immune function, and altered respiratory mechanics, which could affect weaning from mechanical ventilation, 36 the impact of sleep disturbances on morbidity and mortality remains unknown 37 ; however, it could worsen the quality of life after discharge. 38,39 Quantitative and qualitative deficiencies have been characterized, including decreased total sleep time, fragmented sleep, as well as altered circadian patterns.…”

Patient Perception of Environmental and Nursing Factors Contributing to Sleep Disturbances in a Neurosurgical Intensive Care Unit

“…Sleep problems in ICU patients are very common (Goodemote 1991;Krachman et al 1995;Fontaine 1998;Puntillo and Casella 1998;Urban 1998;Freedman et al 1999;Redeker 2000; 22.7 * More than one factor could be chosen in answer to the question to determine factors affecting sleep in the NSICU. Freedman et al 2001;Olson et al 2001;Frisk and Nordstrom 2003;Parthasarathy and Tobin 2004;Lusk and Lash 2005;Peruzzi 2005;Stockert 2005).…”

“…Pain is one of the significant factors negatively affecting sleep and disturbing the normal sleep and wakefulness cycle (Dracup and BryanBrown 1995;Krachman et al 1995;Bucher 2004). Wong and Arthur (2000) reported that patients in the surgical ICU in the early postoperative period not only complained of pain at the wound site, but also stated that they had back pain, and wanted to be given a massage before sleep and pillows to help with positioning.…”

“…Although there are many studies (Krachman et al 1995;Freedman et al 1999;Calvete et al 2000;Freedman et al 2001;Olson et al 2001;Bohrer et al 2002;Gabor et al 2003;Frisk and Nordstrom 2003;Richardson 2003;Parthasarathy and Tobin 2004) reported in the literature studying sleep issue in ICUs, there is only one study capturing the factors that affect sleep in the neurosurgery intensive care unit (NSICU) (Monsėn and Edėll-Gustafsson 2005). In their study, only eight general and ten specific nursing care interventions were investigated.…”
