Objective To study the nursing points of using semiconductor laser to cure early glottis cancer.Methods Retrospective analyzed the nursing cares of 31 patients who have accepted the semiconductor laser operation to cure early glottis cancer.Results There were no postoperative complications among the 31 patients.Conclusion Nursing measures included mental nursing,respiratory management,monitoring the vital signs can effective advance the recovery of patients with early glottis cancer.

OBJECTIVE: To explore the mechanism of Sanqi Qiancao Recipe (SQR) in treating metrorrhagia caused by copper intrauterine device (IUD) in rabbits and to provide experimental evidence for preventing and treating this disease. METHODS: Fifty-six rabbits were randomly divided into seven groups, which were normal control group, sham-operation group, untreated group, indomethacin-treated group, low-dose SQR-treated group, medium-dose SQR-treated group and high-dose SQR-treated group. Copper IUD insertion was operated in rabbits of the last five groups. Rabbits in the last four groups were treated orally with indomethacin and low-, medium- and high-dose SQR respectively for a week. Rabbits in the untreated group, normal control group and sham-operation group were given distilled water orally. Hematocrit, blood viscosity at low, medium and high shear rate, plasma viscosity and blood sedimentation were examined after treatment. RESULTS: The hematocrit, blood viscosity at low, medium and high shear rate and plasma viscosity were higher in the untreated group than those in the normal control group with significant differences (P<0.01) while those indexes in low-, medium- and high-dose SQR-treated groups were significantly lower than those in the untreated group (P<0.05 or P<0.01). CONCLUSION: SQR can lead to a decrease in blood viscosity and improve the blood flow, which may be one of the mechanisms of SQR in treating metrorrhagia after copper IUD insertion.

Objective To observe the effect of hot compress with medicinal salt pack in preventing PICC-associated mechanical phlebitis.Method Totally 200 inpatients undergone PICC intubation were randomized into a treatment group and a control group, 100 cases in each group. After PICC intubation, the treatment group was intervened by hot compress with medicinal salt pack, while the control group was by hot compress with warm wet towel. The occurrence of mechanical phlebitis was observed at different time points and compared between the two groups. Result The occurrence rate of mechanical phlebitis was 9.0% in the treatment group versus 26.0% in the control group, and the difference was statistically significant (P<0.05). In the treatment group, the occurrence rate of mechanical phlebitis was respectively 6.0% and 3.0% when treatment≤72 h and>72 h, versus 16.0% and 10.0% in the control group, and the differences were statistically significant (P<0.05). Conclusion Hot compress with medicinal salt pack can effectively reduce the occurrence of PICC-associated mechanical phlebitis.

Objective To investigate the reasons and nursing countermeasures of the discomfort of peripher-ally inserted central catheter(PICC)intubation patients in the process of placing tube.Methods 290 patients with PICC who were treated with PICC for the first time were summarized.Results 290 patients with PICC in catheter had not comfortable experience.The main reason of causing discomfort was psychological factors,accounted for 90.0%, catheter when the cold experience leads to the discomfort of 82.8%,catheter environmental factors accounted for 6 3 .8 % ,pain caused by discomfort accounted for 15.5% ,puncture posture factors leading to 13.1% .Conclusion The causes of discomfort in the process of PICC is more,strengthen preoperative health education and the operation of effective communication,to create a relaxed comfortable environment to help patients take comfortable posture,improve a catheter success rate,preventing catheter during cold and other measures can improve the patients'comfort.

Objective To investigate the therapeutic effect of injection of dexamethasone solution on the mechanical phlebitis induced by PICC through a syringe pump on intravenous branch of the PICC puncture point.Methods A total of 90 patients who met the criteria were divided randomly into experimental group (n=45) and control group (n=45). Patients in the experimental group were injected on the forearm below the PICC puncture point,where was with good elasticity and obvious exposure,without damage or inflammation,easily fixed,and away from joints or end of tendons. 40 ml of dexamethasone solution,with concentration of 0.125 mg/ml,was injected by a syringe pump with scalp needle 5.5#,with an infusion speed of 10 ml/h,1 time/day. For 3 days of continuous use,the needle was withdrawn once the infusion was done,and the injection location was different for each day. If the mechanical phlebitis was cured after 1 day or 2 days of medication,the injection stopped instantly. For patients in the control group,a wet hot towel was compressed above the PICC point, 3 times/day,20 mins/time. After the application,Hirudoid ointment was rubbed on the side of the upper arm where the catheter was injected,3 days of continuous use was conducted. Observation was conducted to both groups until the 7th day after intervention measures were taken.Results There were significant differences in terms of cure rate and cure time between the two groups (P<0.05) in the treatment of mechanical phlebitis. Conclusions It is highly effective to treat mechanical phlebitis induced by PICC by injection of dexamethasone solution through a syringe pump on intravenous branch of the PICC puncture point,which can relieve symptoms of patients,reduce their pain within a shorter time.
