Early Out-of-Bed Rehabilitation in Severe Psittacosis to Enhance Recovery in Critical Care: A Case Report

BACKGROUND Rehabilitation in critical care (RIC), especially early mobilization (EM), is increasingly recognized as beneficial for critical care patients. However, high-quality and systematic implementation of RIC still requires exploration, as protocols for EM vary among clinical centers. CASE REPORT This study aimed to review the RIC for a patient with severe psittacosis, along with relevant literature, to provide valuable clinical insights for RIC, especially the out-of-bed (OB) RIC. After treatment with antibiotics, optimization of concurrent interventions, nutritional therapy, and bed-based activities, the arterial partial pressure of oxygen ratio fraction of inspired oxygen (P/F ratio) gradually increased to 140 mmHg. Subsequent initiation of OB activities led to a further elevation of this index to 240 mmHg, with successful weaning from mechanical ventilation achieved on the 12th day of hospitalization. These indicators also improved with OB RIC, such as regulation of inflammatory response, promoted anabolism, and supported the recovery of respiratory function and motor abilities. CONCLUSIONS The recovery of critical care patients depends on multiple factors, among which RIC is indispensable. EM is an important component of RIC. From this case, we hypothesize that OB can further enhance the quality and efficacy of RIC. We look forward to more studies focusing on OB. The present report describes the implementation of OB using structured and quantifiable indicators: OB percentage (OBP), OB time (OBT), and OBT proportion (OBTP).
