Objective:To explore the enhancement effect of two different bed-moving modes and their relative parameters in children's chest CT checkup.Methods:The enhancement of out-bed group was studied with the in-bed group as control and the mean data of the major parameters were acquired.Then the enhancement effect and the major parameters were analyzed to make clear the differences presented in the two groups.Results:No difference was found between the two groups in enhancement effect and the data of major parameters.Conclusion:For each bed-moving mode,enhancement effect relied on the reasonable determination of the integrative parameters,but not a single one.

Objective:To explore the efficiency of comprehensive sedation nursing in MRI examination to the epilepsy children underthe age of 4.Methods:180 children were randomly divided into the test group and the control group.The test group was given comprehensive sedation nursing,while the control group was only given the simple drug sedation by oral medicine called 10%chloral hydrate.The effective rate,the time children fell to sleep after given the drug and one-time success rate were recorded and analyzed between the two groups.Results:The effective rate,the time children fell to sleep after giving the drug and one-time success rate all have siganificant difference between these two groups(P

Objective To study the characters of using the high pressure injector in the contrast CT scanning for children. Methods Summarized the nursing measures of 407 children who had accepted the contrast CT scanning. Results There were 369 children have obtained perfect effects of CT scanning, 35 children have obtained general effects and there were 2 children failure. Conclusion The method of using high pressure injector in the contrast CT scanning for children is convenient, safety and effective.

Objective To investigate the effect of ultrasound-guided quadratus lumborum block (QLB) on postoperative analgesia after caesarean section.Methods Sixty parturientsscheduled for cesarean section, aged 20-40 years, ASA physical status Ⅰ orⅡ, were randomly divided into 2 groups (n = 30 each) using a random number table:QLB group (group Q) and control group (group C).Parturients in group Q received bilateral QLB with the use of 20 ml 0.33％ ropivacaine per side after surgery, while QLB was not done in group C.Both groups received patient-controlled intravenous analgesia (PCIA) after surgery which contains 800 mg tramadol, 40 mg nefopam and 80 ml normal saline.The accumulative consumption of tramadol, the score of numerical rating scale (NRS) for pain at rest and on movement and the bruggrmann comfort scale (BCS) score were recorded at 4, 8, 12, 24, 48 hafter operation.The cutaneous sensory block area was determined in group Q at 4, 8, 12, 24, 48 hafter operation.The patient′s satisfaction with postoperative analgesia and adverse reactions were also recorded.Results The consumption of tramadol in group Q was significantly decreased compared with that in group C (P<0.05) at 4, 8, 12, 24, 48 hafter surgery.NRS for pain at rest at all times, NRS for pain when cough at 12, 24 hafter surgery and NRS for pain when turning over at 4, 48 hafter surgery were significantly lower, while the BCS score was higher in group Q than that in group C (P<0.05).Quadratus lumborum block affected T7-L1 dermatomes at 4, 8, 12 hafter surgery and T8-L1 dermatomes at 24 hafter surgery.The analgesic plane of quadratus lumborum block disappeared at 48 hours after operation.The patient's satisfaction with postoperative analgesia was higher in group Q compared with that in group C (P<0.05).The incidence of postoperative nausea, vomiting and dizziness was similar between the two groups.Conclusion Ultrasound-guided quadratus lumborum block can remarkably reduce the consumption of tramadol after caesarean section, lower the postoperative pain score, improve the patient′s comfort and satisfaction.
