Following total knee replacement (TKR) surgery, patients frequently experience intense levels of pain, stress, and anxiety that may reduce their self-efficacy and thus affect their postoperative recovery. Relaxation intervention is beneficial to help patients manage physical pain and emotional tension. However, evidence for the efficacy of relaxation intervention on patients following TKR is still inconclusive. ⋯ Following the intervention, participants reported significantly lower pain, stress, and anxiety and greater perceived relaxation and self-efficacy. Findings from this study contribute to both nursing science and clinical practice. The relaxation intervention can be offered as part of standard care for patients following TKR in hospitals.

Comparative StudyEffects of ketoprofen for prevention of postoperative cognitive dysfunction in aged rats.
Postoperative cognitive dysfunction is a common geriatric complication that may be associated with increased mortality. Here, we investigated the effects of postoperative analgesia with ketoprofen on cognitive functions in aged animals and compared its effectiveness to morphine. Rats were randomly allocated to one of four groups: isoflurane anesthesia without surgery (group C), isoflurane anesthesia with laparotomy (group IL), and isoflurane anesthesia with laparotomy plus postoperative analgesia with ketoprofen or morphine. ⋯ However, both ketoprofen and morphine could attenuate the increase in memory errors following surgery to a similar degree. Conversely, ketoprofen showed no effect on cognitive function in the nonsurgical rats that did not experience pain. Our findings suggest that postoperative analgesia with ketoprofen can prevent the development of surgery-associated memory deficits via its pain-relieving effects.

Clinical TrialNon-invasive cardiac output evaluation in postoperative cardiac surgery patients, using a new prolonged expiration-based technique.
The gold standard methods to measure cardiac output (CO) are invasive and expose the patient to high risks of various complications. The aim of this study is to assess an innovative non-invasive method for CO monitoring in mechanically ventilated patients after cardiac surgery and its agreement with values obtained by thermodilution technique. Continuous monitoring of respiratory gas concentrations and airflow allows the estimation of CO through a newly developed algorithm derived from a modified version of the Fick equation. ⋯ COK shows a mean percentage error of 34 %. In stable mechanically ventilated patients, undergone cardiac surgery, the proposed method is reliable if compared to the thermodilution. Considering the non-invasivity of the technique, further evaluations of its performances are encouraged.
