Abstract
OBJECTIVE This study aimed to observe the application effect of emergency treatment mode of damage-control orthopedics (DCO) in pelvic fracture complicated with multiple fractures. METHODS Ninety-four patients with pelvic fracture complicated with multiple fractures in our hospital were recruited and divided into two groups according to the random number table method, with 47 cases in each group. Patients in the control group received traditional methods for emergency treatment (early complete treatment), and patients in the research group received DCO for emergency treatment (treatment performed in stages according to patient's physiological tolerance, with simplified initial surgery, followed by ICU resuscitation, and finally definitive surgery). The two groups were compared in terms of mortality, the incidence of acidosis and hypothermia three days after the first surgery, surgery-related indexes (time of the first surgery, blood transfusion volume, intraoperative blood loss, recovery time of temperature, and length of hospital stay), coagulation function indexes (activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT) and fibrinogen (FIB)), postoperative reduction of fracture, complication rate, and quality of life. RESULTS The incidences of acidosis, hypothermia, and mortality three days after the first surgery in the research group were lower than those in the control group (P<0.05). Compared with the control group, the research group experienced shorter time of the first surgery, less intraoperative blood transfusion volume, less intraoperative blood loss, shorter recovery time of body temperature, and shorter length of hospital stay (P<0.05). Seven days after surgery, PT, TT and APTT decreased and FIB increased in both groups (P<0.05), PT, TT and APTT in the research group were lower than those in the control group (P<0.05), while FIB was higher (P<0.05). The good rate of reduction in the research group was higher than that in the control group (P=0.025). The incidence of complications in the research group was lower than that in the control group (P=0.049). Six months after surgery, the scores of physiological function (PF), body pain (BP), role physical (RP), emotional function (EF), social function (SF), vitality, and general health (GH) of the research group were higher than those of the control group (P<0.05), but there was no significant difference in mental health (MH) between the two groups (P>0.05). CONCLUSION The emergency treatment mode of DCO is effective in pelvic fracture complicated with multiple fractures, which can effectively improve postoperative reduction of patients, improve the coagulation function, reduce complications, and improve the quality of life.

Abstract
BACKGROUND Laryngomalacia is the most common cause of stridor in neonates and infants, and supraglottoplasty is the mainstay of surgical treatment. Although low-temperature plasma radiofrequency ablation (LTP-RFA) using coblation technology has been used for treating laryngomalacia, it is still lack of high-quality clinical evidence. Therefore, we conduct this prospective randomized study to clearly define the role of LTP-RFA for the treatment of laryngomalacia in neonates and infants. METHODS Between Jan 2017 and Dec 2019, a total of 89 children with laryngomalacia were included for analysis. All patients were initially stratified according to the severity of laryngomalacia. Patients with severe laryngomalacia were randomly assigned to receive LTP-RFA or traditionally surgical supraglottoplasty, while patients with moderate laryngomalacia were assigned to LTP-RFA or observation. The primary end point was the efficacy and toxicities of LTP-RFA by assessing the changes of clinical score and visual analogue scale (VAS) symptom score. The total score was the combination of clinical score with VAS score. RESULTS Of the 89 children, 40 children presented with severe laryngomalacia, and the remaining 49 children were diagnosed as moderate laryngomalacia. The median age was 68 days (range, 19 to 337 days). For children with severe laryngomalacia, our results showed that LTP-RFA treatment significantly reduced the operative time (5.55±1.66 vs. 18.7±5.31 min, P<0.001), length of hospital stay (6.71±1.15 vs. 7.95±1.55 days, P=0.008) and the amount of intraoperative hemorrhage (1.71±1.79 vs. 4.90±1.82, P<0.001) when compared to traditionally surgical supraglottoplasty, while the treatment efficacy was comparable between LTP-RFA and traditionally surgical supraglottoplasty in terms of changed total score (P=0.322), changed clinical score (P=0.135) and changed VAS symptom score (P=0.559). Additionally, for children with moderate laryngomalacia, LTP-RFA treatment significantly improved the symptom evaluated by total score (P<0.001), clinical score (P<0.001) and VAS symptom score (P<0.001) in comparison with the observation group. Post-operative pneumonia was observed in 10 patients. No surgical related death was reported. CONCLUSIONS The present study indicated that LTP-RFA was an effective treatment option for both severe and moderate laryngomalacia in neonates and infants with a low intraoperative complication. Long-term outcomes of LTP-RFA for laryngomalacia would be reported in further studies.
