ABSTRACT
Objective To investigate the hemostasis effect of alginate dressing for puncture point bleeding after peripherally inserted central catheter (PICC) by ultrasound-guided modified Seldinger technique (MST).Methods Between November 2013 and May 2016, 538 cases of cancer in our department underwent PICC, including 270 cases from November 2013 to February 2015 selected as control group (after PICC was successfully placed, sterile gauze and 3M transparent film were used to fix the puncture point) and 268 cases from March 2015 to May 2016 selected as observation group (after PICC was successfully placed, alginate dressing, sterile gauze and 3M transparent film were used to fix the puncture point).The patients in both groups were given 20 minutes of pressure for puncture point and elastic bandage compression fixation for 24 h.The degree of puncture point bleeding and times of dressing change in 24 h and 24-72 h between the two groups were compared.Results In the observation group, mild, moderate, and severe bleeding was seen in 232 cases, 34 cases, and 2 cases within 24 h, and in 242 cases, 25 cases, and 1 case between 24-72 h, respectively.In the control group, mild, moderate, and severe bleeding was seen in 12 cases, 196 cases, and 62 cases within 24 h, and in 21 cases, 212 cases, and 37 cases between 24-72 h, respectively, with significant differences (Z=-18.647, P=0.000;Z=-18.768, P=0.000).In the observation group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 232 cases, 33 cases, 3 cases, and 0 case within 24 h and in 242 cases, 25 cases, 1 case, and 0 case between 24-72 h, respectively.In the control group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 12 cases, 196 cases, 51 cases, and 11 cases within 24 h and in 21 cases, 209 cases, 37 cases, and 3 cases between 24-72 h, respectively, with significant differences (Z=-18.560, P=0.000;Z=-18.755, P=0.000).Conclusion The hemostasis effect of alginate dressing for puncture point bleeding after ultrasound-guided PICC by MST is satisfactory.
ABSTRACT
Objective To observe the curative effect of soft silicone dressing combined with calcium alginate dressing for treatment of skin graft donor sites of burned patients. Methods A total of 80 burned patients were randomly divided into treatment group (n=39) and control group (n=41). In the treatment group the donor sites were covered with calcium alginate dressing (Sorbalgon) inside and soft silicone dressing (Mepilex) outside, and the donor sites in the control group were covered with chlorhexidine gauze inside and multilayer sterile gauze outside. The wound healing, pain improvement and scar formation were evaluated in the two groups. Results The wound healing rates at post-operative 7, 10 and 12 d in the treatment group were significantly higher than those in the control group (treatment group:[51. 31±7. 09]%, [78. 77±8. 80]% and[96. 44±3. 24]%; control group:[45. 85±5. 54]%, [73. 63±7. 73]% and[93. 12±4. 08]%; P<0. 01). The wound healing time of the treatment group was significantly shorter than that of the control group ([10. 95±1. 41] d vs[11. 93±1. 44] d, P<0. 01). Visual analogue scale (VAS) scores at post-operative 1, 3, 7 and 10 d in the treatment group were significantly lower than those in the control group (treatment group:5. 36±1. 21, 4. 29±1. 25, 4. 00±0. 46 and 1. 00±0. 45; control group:7. 34±1. 34, 5. 89±1. 39, 4. 50±0. 74 and 1. 35±0. 52; P<0. 01). The Vancouver scar scale (VSS) scores at post-operative 1, 3, 6 and 12 month in the treatment group were also significantly lower than those in the control group (treatment group:3. 82±1. 47, 6. 00±1. 61, 3. 77±2. 28 and 2. 59±1. 39; control group:5. 80±1. 68, 7. 80±1. 65, 5. 24±1. 67 and 4. 05±1. 41; P<0. 01). Conclusion Soft silicone dressing combined with calcium alginate dressing in treatment of the skin graft donor sites can greatly improve the wound healing rate, shorten the wound healing time, relieve pain in dressing change and improve the wound healing quality, and it may serve as an effective method for protecting the donor sites.
ABSTRACT
Objective To assess the efficacy of alginate dressing in fat liquefaction of abdominal incision. Methods 76 patients with fat liquefaction of abdominal incision in our hospital were divided into the experimental group (42 patients) and the control group(34 cases). Both groups were given preventive antibiotics. The penetration, times of dressing change, interval of dressing change, healing cost, wound infection, period Ⅱ wound healing, time for the medicine to start working, time of healing were observed in the two groups. All results underwent t test and χ2 test. Results No distinct difference of healing cost between the two groups was observed. The experimental group treated with alginate dressing was better than the control group in other clinical indexes after treatment. Conclusions Application of alginate dressing is beneficial to management of fat liquefaction of abdominal incision and reduce time of healing and hospital stay.
