Along with the accumulation of evidence to support the use of an oral rehydration solution before surgery, there is a strong tendency for the period of fasting before the induction of general anesthesia to become shorter and shorter. In this study, we compared hunger, thirst, psychology and onset of pneumonia as a sequela in between two groups of surgical patients-one with preoperative rehydration and the other without. The results showed that stress did not build up in the patients given a preoperative oral rehydration solution even after they returned to their rooms and did not have an intravenous drip. No one in either group developed pneumonia after surgery.

Background: Mental assessment for patients in a palliative care unit with no regular psychiatrist tends to depend on subjective judgments by other health professionals. We introduced the 9-item Patient Health Questionnaire (PHQ-9) to screen major depression from patients in a palliative care unit and assessed the usefulness of the questionnaire. Methods: The subjects were all patients who were admitted to a palliative care unit. Each patient was asked to answer the PHQ-9 on admission and then was interviewed by a psychiatrist. When PHQ-9 score was of 10 points and above, the case was judged to be positive for depressive disorder. A psychiatrist diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5). Results: A total of 83 patients were hospitalized between January 2016 and October 2016. 50 patients completed PHQ-9 and psychiatrist’s interview. Nine cases were positive by PHQ-9 and diagnosed as depressive disorder by a psychiatrist. Seven cases were positive by the PHQ-9 but not diagnosed as depressive disorder. Although 34 cases were judged to be negative by the PHQ-9, 2 cases of them were diagnosed as depressive disorder. The sensitivity and specificity of the PHQ-9 were 81.8% and 82.1% respectively. Conclusion: We found that the PHQ-9 was useful screening test for depression even in palliative care settings.
