Objective To summarize the latest development of the oral and maxillofacial reparative and reconstructive surgery. Methods The literature at home and abroad was reviewed and the main creative concepts in this field were summarized and analyzed. Results In the terms of the oral and maxillofacial reparative and reconstructive surgery, the significant achievements were made in the following aspects: transplantation of revascularized tissues, artificial materials, plateletrich plasma, distraction osteogenesis, microsurgery on fracture, arthroplasty, dynamic repair, and computerassisted design. Conclusion Based on the previous achievements, the oral and maxillofacial reparative and reconstructive surgery will have a further development, especially in the individualized treatment.
Objective A systematic review was conducted based on the domestically published literature for improving the quality of oral nursing care.Methods The terms "oral nursing care", "oral hygiene care", "mouth care" were used to search related studies in Chinese databases (up to April 30, 2004) along with handsearching additional studies. Four authors screened and selected the studies, appraised the methodological quality and extracted data from these selected studies. The results were presented by description or Meta-analysis. Results A total of 28 studies were identified, of which 6 were excluded. The methodological quality varied among the studies, 7 scored as B, 15 as C (11 randomized controlled trials, 4 quasi-randomized trials). A total of 2 372 patients were observed including some were critically ill, or intubated, or receiving radiotherapy or chemotherapy or undergoing surgical operations.Six authors of RCT replied and four of them provided more information on methods of randomization. Data analysis revealed that traditional oral nursing procedure was suitable for the severely sick patients who could not take self-care. Brushing and gargling were suitable for conscious patients who could use their hands. Tea and toothpaste were safe, economical and convenient oral nursing agents. Oral pH was a useful index for the selection of oral nursing agents and mouthwashes. A gargle containing sodium bicarbonate was used in the acidic oral environment and reduced fungal infection. The mouthwash with tea polyphenols had good effect for oral health, and might be as the first choice for prophylaxis of stomatitis induced by radiotherapy and/or chemotherapy. Some mouthwashes developed by Chinese herbs improved oral health efficiently. Some disinfectants with good safety and low toxicity might be used as supplementary agents in oral nursing care. Conclusions Oral nursing care procedures have improved the efficiency of oral care. But the conclusion should be verified by more, well designed randomized controlled trials involving a collaborative multidiscipliary health care professionals. Oral nursing care practice needs to be evidence based.
The wister rats with cirrhotic portal hypertension induced by carbon tetrachloride/ethanal were divided into four groups;①distal splenocaval shunt(DSCS);②portal azygous devascularization (PAD);③mesocaval shunt side to side (MCS);and ④the conrol. Oral glucose toleronce test (OGTT), and glucagon loading test (GLT) were performed on them. The results revealed that the hepatic reserve function of the rats with DSCS and PAD had significant difference as compared with the control (Ｐ＜0.05), but that of the rat with MCS had no significant difference as compared with the control (Ｐ＞0.05).The present study indicates that the hepatic reserve function of rats with DSCS and PAD is better than that of the rats with MCS.
Objective To investigate the thirst status of patients in intensive care unit (ICU) who underwent oral tracheal intubation and ventilator assisted ventilation, and explore its influence factors. Methods A total of 172 patients with oral tracheal intubation admitted in ICU from June 2020 to September 2021 were investigated, and a numerical rating scale was employed for rating their thirst feelings. The patients were divided into a thirst group and a non-thirst group based on thirst status. The thirst status and influence factors of thirst distress were analyzed. Results The incidence of thirst in the ICU patients with oral tracheal intubation and ventilator assisted ventilation was 88.4%, and the thirst score in the thirst group was 7.70±1.17. Single factor analysis showed statistically significant difference between the two groups in sex, medical payment, smoking, drinking, duration of mechanical ventilation, humidification effect, sputum viscosity, gastrointestinal decompression, fasting, continuous renal replacement therapy, diuretics, 24-hour urine volume and liquid balance, heart function grading, sedatives, agitation, sweating, acute physiology and chronic health evaluation Ⅱ, endotracheal intubation depth, body mass index, PCO2, PO2, HCO3–, tidal volume, and sodium ion (all P<0.05). Multivariable regression analysis demonstrated that diuretics, sputum viscosity, sodium ion, alcohol consumption, smoking, intubation depth, and cardiac function were independent influence factors for the occurrence of thirst in the ICU patients who received tracheal intubation (P<0.01). Conclusions The incidence of thirst was high in ICU patients with airway intubation and ventilator assisted ventilation. Diuretics, sputum viscosity, sodium ion, alcohol consumption, smoking, 24-hour urine volume, and cardiac function grading were independent influence factors for the occurrence of thirst in ICU patients with tracheal intubation. It is necessary to implement targeted intervention to prevent and alleviate the thirst degree of patients, reduce the occurrence of related complications, and improve patient comfort.
Resuming oral anticoagulant (OAC) after intracerebral hemorrhage (ICH) is still a dilemma to clinical decision. To date, no high-quality randomized controlled trials demonstrate the timing and mode of safely resuming OAC. In recent years, some moderate-quality researches have suggested that OAC resuming after ICH can decrease the incidence of thromboembolic events and long-term mortality, without significantly increasing the risk of ICH; it is safer to resuming OAC in patients with non-lobar ICH than in patients with lobar-ICH; new OACs are superior to vitamin K antagonists; patients with high thromboembolic risk should resume OAC 2 weeks or even earlier after ICH, otherwise, a time-window for optimal resumption is between 4-8 weeks; meanwhile, individual patient characteristics should be considered and blood pressure should be strictly controlled.
ObjectiveTo systematically review the efficacy of transdermal fentanyl versus oral morphine for moderate/severe cancer pain. MethodsDatabases such as The Cochrane Library (Issue 1, 2014), PubMed, Web of Science, CNKI, VIP, CBM and WanFang Data were searched for randomized controlled trials (RCTs) on the efficacy of transdermal fentanyl versus oral morphine for moderate/severe cancer pain up to January 2014. According to inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed methodological quality of included studies. Then meta-analysis was performed using RevMan 5.1.0 software. ResultsA total of 35 RCTs involved 3 406 patients were included. The results of meta-analysis showed that, there was no significant difference in effectiveness between transdermal fentanyl and oral morphine for moderate/severe cancer pain (OR=1.00, 95%CI 0.80 to 1.27, P=0.99). Compared with oral morphine, transdermal fentanyl was better in lowering the incidences of constipation, nausea and vomiting, lethargy and urinary retention; but transdermal fentanyl increased the incidences of skin rashes and itch (P < 0.05). ConclusionTransdermal fentanyl is as effective as oral morphine in the treatment of moderate/severe cancer pain, and transdermal fentanyl causes less side effects. Due to poor quality of the included studies, the above conclusion should be verified by further conducting more high quality RCTs.
Objective?To explore the glucometabolic state of angiographically documented inpatients with coronary artery disease (CAD) but without diagnosed diabetes mellitus (DM). Methods?The study recruited 449 patients, who were performed a coronary angiography as well as an oral glucose tolerance test (OGTT) when admitted in the cardiovascular medical ward in our hospital from January 2007 to May 2009. According to the results of coronary angiography, the patients were divided into a coronary artery disease (CAD) group and a non-coronary artery disease (non-CAD) group, and abnormal glucose metabolism (AGM) status was compared between the two groups. Results?The random plasma glucose (RPG) and fasting plasma glucose (FPG) had no significant differences (P values were 0.249 and 0.444, respectively) in the two groups, while the OGTT 2-hour plasma glucose (2hPG) was much higher in the CAD group, with a significant difference (Plt;0.001) compared with the non-CAD group. The CAD group had a prevalence of AGM up to 74.0%, of which 32.1% were newly diagnosed DM patients, and 39.0% were impaired glucose tolerance (IGT) patients, much higher than that in the non-CAD group, respectively, there being a significant difference (P=0.006). Logistic regression analyses revealed that the risk of IGT and newly diagnosed DM was 1.6 times (OR=1.603, 95% CI 1.023 to 2.512, P=0.04) and 2.3 times (OR=2.292, 95% CI 1.391 to 3.777, P=0.001) as much as that in non-CAD patients, respectively; when adjusted for the factors such as hypertension, dyslipidemia, BMI, hs-CRP, and other factors, CAD patients still had a higher risk of newly diagnosed DM (OR=1.852, 95%CI 1.064 to 3.223, P=0.029), compared with the non-CAD patients. Conclusion?AGM is common in the admitted patients with CAD but undiagnosed diabetes, most of whom need an OGTT to be diagnosed timely and accurately. OGTT should be considered to be a routine inspection item to diagnose AGM in the inpatients with CAD; if possible, all hospitalized patients with cardiovascular disease should be performed an OGTT routinely.
Objective To investigate cl inical effect and prognosis of the modified sternocleidomastoid (MSCM) myocutaneous flap for reconstruction of tissue defects in patients with oral carcinomas undergoing tumorectomy. Methods From April 2001 to January 2007, 43 patients with large or medium-sized tissue defects because of oral carcinomas radical operation were treated with MSCM myocutaneous flap. There were 31 males and 12 females with an average age of 58.5 years(25-76 years). The disease course was 25 days to 14 months (4.5 months on average). There were 27 cases of well-differentiated squamous cell carcinoma (SC), 14 cases of poorly-differentiated SC, 1 case of rhabdomyosarcoma, and 1 case of adenoid cystic carcinoma. Affected locations were tongue in 25 cases, mouth floor in 11 cases, lower gingiva in 4 cases, and buccal mucous membranes in 3 cases. According to 2002 International Union Control Cancer criterion for cl inical stage, there were 3 cases of stage I, 13 cases of stage II, 7 cases of stage III, and 20 cases of stage IV. Both the ranges of soft tissue defects and the flap were from 4 cm × 3 cm to 8 cm × 6 cm. The vital ity of the flaps and the heal ing of wounds were observed postoperatively. The function restoration of deglutition and dehisce were observed during the follow-up period. Results Necrosis of quarter MSCM myocutaneous flap occurred in 3 cases 1 week after operation, wounds healed by secondary intention after dressing; other flaps were survival. Infection with fluidify occurred at the donor site of 2 cases, wounds healed by incision and drainage; other incision at the donor sites healed primarily. No arterial or venous crisis occurred in all 43 flaps after 48 hours of operation. Thirty-nine patients were followed up for 6 months to 6 years. The 3 patients with buccal carcinoma could open their mouths normally. The function of deglutition and pronunciation were recovered in 24 patients with tongue carcinoma. Only 3 patients needed to have soft diet after operation. In 26 patients who were followed up above 2 years, oral metaplasia of the the skin flaps epithel ium was observed. Four patients and 2 patients recurred and died after 6 months and 1 year of operation, respectively.Two patients received the second operation after 6 months because of the metastatic lymph node, and survived up to now. The 2-year survival rate was 85%. Conclusion MSCM myocutaneous flap is simple to perform and effective in reconstruction of tissue defects for patients with oral carcinomas. It has active effect to recover the function of oral and axillofacial region and elevate l iving qual ity of patients.
Objective To investigate the clinical effect ofthe pectoralis major myocutaneous flap and Ti-plate system in repairing mandibular defects caused by resection of oral carcinoma.Methods From November 2001 to February 2003, 32patients with mandibular defect caused by resection of oral carcinoma were treated. Combined radical neck dissection with resection of gingival and mandible was performed on 11 patients with carcinoma of the lower gingival, combined radical neck dissection with glossectomy and mandibulectory on 13 patients with carcinoma of tongue, combined radical neck dissection with resection of floor of mouthand mandible on 4 patients with carcinoma of floor of mouth, and combined radical neck dissection with resection of cheek and mandible on 4 patients with carcinoma of buccal mucosa, respectively. The defects of mandible were associated with soft-tissue component, the sizes of defect ranged from 5.5 cm×7.6 cm to 8.2 cm×10.5 cm. The defects were reconstructed with 6 cm×7 cm to 9 cm×10 cm pectoralis major myocutaneous flaps and Tiplate system. The effect was studied retrospectively. Results Thirty-two cases were followed for 219 months; 29 cases offlaps survived and 3 cases of flaps partly necrosed (10% or less of the skin paddle). The appearance of face was satisfactory in 27 patients, and slight deformity of face was observed in 5 patients. The occluding relation and masticatory function were recovered well. Opening mouth extents ranged from 2.7 cm to 3.4 cm. No temporomandibular arthrosis relating to operation was found in all cases. Conclusion A combination of thhe pectoralis major myocut aneous flap and Ti-plate system is an ideal method for reconstruction of mandible defects associated with soft-tissue component after radical operation of oral carcinoma.
