Objective To evaluate the trust level of nurse-patient relationship and analyze its influencing factors.Methods Trust level of nurse-patient relationship scale was used to investigate 136 inpatients.The factors influencing trust level of nurse-patient relationship was analyzed.Results Of the 136 inpatients,the scores of the five dimensions of trust scale ( knowledge and technology trust,eonsistoncy,respect,sense of peace of mind and confidence in the future ) were:(3.62 ± 0.26),( 3.47 ± 0.32 ),( 3.59 ±0.61 ),(3.58 ± 0.73 ),( 3.35 ± 0.79 ),respectively.The item of maximum score was" After ring the hell,nurses respond quickly" (3.92 ±0.35),and the item of lowest score was "Nurses have too many commands on me,I feel uneasy and not free" (2.75 ± 0.10).Regression analysis showed that age ( t =11.940,P ＜ 0.05 ),hospitalization duration ( t =2.537,P ＜ 0.05 ) and type of payment ( t =4.362,P ＜ 0.05 ) were the major influencing factors of nurse-patient relationship in the patients' point of view.Conclusions The nurses should pay attention to the factors that affect nurse-patient relationship,and further cnhance trust level of nurse-patient relationship by improving care measures.

OBJECTIVETo investigate the effects, side-effects and security of bupivacaine, ropivacaine combined with fentanyl in postoperative continuous epidural analgesia.

METHODSA total of 1 600 postoperative continuous epidural analgesia patients receiving different agents in SICU were divided into two groups: 0.1% bupivacaine +5 microg/ml fentanyl group (group B, n = 920) and 0.2% ropivacaine +2 microg/ml fentanyl group (group R, n = 680). The effects (visual analog-scale score and content to analgesia), side effects were analyzed retrospectively in the two groups.

RESULTSCompared with group B, patients in group R had higher analgesia contentment (P < 0.05), but no difference in visual analog-scale score was found in the two groups. The incidences of urinary retention, nausea and vomiting, skin itching in group B were significantly higher than those in group R (P < 0.05). In each group, patients over sixty had higher ratio of hypotension than those under sixty (P < 0.05); The female patients had a higher incidence of nausea and vomiting than male patients (P < 0.05); The incidence of debility and numbness of lower limbs in patients with lumbar segments epidural analgesia was higher than those with thoracic analgesia (P < 0.05).

CONCLUSIONS0.1% bupivacaine +5 microg/ml fentanyl and 0.2% ropivacaine +2 microg/ml fentanyl can provide adequate pain relief in postoperative continuous epidural analgesia, and 0.2% ropivacaine +2 microg/ml fentanyl comes with less side effects. The incidence of complication is related with analgesics, age, gender and the position of epidural puncture.
