Dynamic assessment of lung injury by ultrasound in a case with H7N9 influenza.

H7N9 influenza is a new emerging infection and has high mortality. Both chest radiography and computed tomography (CT) had some limitations in assessing such patients. We performed daily lung ultrasound in a patient with H7N9 influenza. Lung ultrasound and lung ultrasound score showed high consistency with CT and the progression of pneumonia. Ultrasound can be adjutant to chest radiography and CT in caring for patients with H7N9 influenza.

[Effect of a novel analgesic disposable urinary catheter in prevention of restlessness caused by catheter-related bladder discomfort in general anesthesia patients in recovery period].

OBJECTIVE: To investigate the effect of a novel analgesic disposable urinary catheter invented by the authors in prevention of restlessness caused by catheter-related bladder discomfort (CRBD) in general anesthesia patients in anesthesia recovery period. METHODS: Two hundred patients, who underwent general anesthesia for general surgical operation, were divided randomly into 2 equal groups: observation group, undergoing insertion of F16 novel analgesic disposable Foley urinary catheter after inducement of general anesthesia, and control group undergoing insertion of conventional F16 Foley urinary catheter after induction of anesthesia. The rate of restlessness caused by CBRD and the rate of catheter pulling-off were compared. RESULTS: The CRBD rate of the observation group was 9%, significantly lower than that of the control group (61%, P < 0.01), the rate of CRBD-caused restlessness of the observation group was 0, significantly lower then that of the control group (23%, P < 0.001). The extent of CRBD of the observation group was significantly lighter than that of the control group. CONCLUSION: The catheter inserting after the induction of anesthesia is an element related to the restlessness in anesthesia recovery period and other serious postoperative complications. The novel analgesic disposable urinary catheter effectively prevents CRBD-caused restlessness in general anesthesia patients in the anesthesia recovery period.
