Early Application Study of Intravenous Pain Pump Combined with Parecoxib Injection in Relieving Pain in Patients after Thoracoscopy

Objective: To explore the clinical effectiveness of combined use of intravenous pain pump with Parecoxib injection in alleviating pain in patients during the early postoperative period after thoracoscopic surgery. Methods: Eighty patients who underwent thoracoscopic surgery in a tertiary hospital were selected as the study subjects and randomly divided into two groups, with 40 patients in each group. The control group received routine postoperative treatment with intravenous pain pump, while the experimental group received Parecoxib in addition to the standard postoperative pain pump treatment. Visual Analog Scale (VAS) pain scores were used to evaluate postoperative pain relief in both groups, along with adverse reactions, postoperative complications, and patient satisfaction with pain relief. Results: Patients who received Parecoxib injection in addition to the routine use of intravenous pain pump had VAS pain scores lower than 3 points at 6 h, 12 h, 24 h, and 36 h postoperatively compared to those in the control group. The incidence of postoperative lung collapse, pleural effusion, and pulmonary infections was also significantly lower in the experimental group. The differences between the two groups were statistically significant (P Conclusion: Early combined use of Parecoxib injection in the early postoperative period after thoracoscopic surgery has shown good clinical efficacy. It can reduce the level of pain in patients, promote effective coughing and expectoration, facilitate early mobilization of patients, improve patient compliance, reduce complications, shorten hospital stay, and expedite patient recovery. Therefore, it is worth promoting the widespread clinical application of Parecoxib injection in this setting.

Application Effect of External Diaphragm Pacemaker Combined with Active Respiratory Circulation Technology in Pulmonary Rehabilitation of Perioperative Lung Cancer Patients

Aim: To explore the application effect of external diaphragm pacemaker combined with active respiratory circulation technology in pulmonary rehabilitation of perioperative lung cancer patients. Methods: A total of 98 lung cancer patients admitted to our hospital from April 2020 to November 2021 were selected as the observation objects, and then divided into a control group and an observation group using the random number table method, with 49 cases in each group. The control group received routine admission guidance and active respiratory circulation training, while the observation group was supplemented with external diaphragm pacemaker on the basis of the control group. The intervention effect was evaluated by blood gas indicators, pulmonary function indicators, diaphragm function indicators, sputum comfort degree, and activity tolerance indicators before and after intervention. Results: Before intervention, there were no significant differences in blood gas analysis indicators, pulmonary function indicators, diaphragm function indicators, sputum comfort degree, and activity tolerance indicators between the two groups (P > 0.05). After intervention, the improvement degree of the above indicators in the observation group was higher than that in the control group (P < 0.05). Conclusions: The application of external diaphragm pacemaker combined with active respiratory circulation technology in pulmonary rehabilitation of perioperative lung cancer patients is significant, which can effectively improve the pulmonary function, blood gas function, and diaphragm function of lung cancer patients after surgery, and improve the activities of daily living and quality of life of patients.

Effects of Video Combined with the Teach-Back Method on the Respiratory Function Exercise of Patients Undergoing Thoracotomy

Objective: To explore the effect of video combined with the teach-back method on respiratory function exercise in patients undergoing tumor thoracotomy. Methods: Eligible patients undergoing thoracotomy for tumor were selected from the thoracic surgery at a level-A tertiary hospital between August 2021 and December 2021 and included in the control group and the observation group (40 patients in each group). To prevent two groups of patients from interacting with each other, the thoracic surgery ward I was distinguished as the control group, which was adopted by the routine instruction. Based on routine instruction, the thoracic surgery ward II conducted respiratory function exercise instruction by video combined with the teach-back method to compare the two groups’ compliance with respiratory function exercise, complication rates, and patient satisfaction. Results: The patient compliance with respiratory function exercise in the observation group was significantly higher (P < 0.05) and the rate of pulmonary complications in the observation group was lower (P < 0.05) than that in the control group, while the observation group had a high level of satisfaction (P Conclusion: Taking video combined with the teach-back method, an effective health education method, can improve the compliance of the respiratory function exercise of patients undergoing thoracotomy for tumor and promote the recovery of pulmonary function to reduce the incidence of postoperative pulmonary complications so as to improve patient satisfaction.

Perioperative Nursing Care for Patients with Lung Cancer Undergoing Total Pneumonectomy

Objectives: To explore the perioperative nursing care for lung cancer patients undergoing total pneumonectomy, and to promote their rehabilitation. Methods: We will provide preoperative assessment and education in the aspects of respiratory function, diet, and psychology to patients undergoing total pneumonectomy, and provide continuous postoperative management about posture, fluid, and respiratory to help patients diagnosed with lung squamous cell carcinoma and underwent total pneumonectomy to reduce their postoperative complications and improve their overall quality of life. Results: 78.9% of lung cancer patients who underwent total pneumonectomy achieved a better outcome and prognosis by receiving the above nursing program. Conclusion: With large lung cancer tumors, the surgical trauma is highly invasive and the resection is extensive. Management of the patient’s respiratory tract is the focus of perioperative nursing and the key to preventing the development of related postoperative complications.

Rare Earth Element Geochemistry of Phosphatic Rocks in Neoproterozoic Ediacaran Doushantuo Formation in Hushan Section from the Yangtze Gorges Area, South China

Phosphatic rocks are widely distributed in Neoproterozoic Ediacaran Doushantuo Formation in Yangtze Gorges Area, South China. In this study, rare earth element geochemistry of eight phosphatic rock samples from the Hushan Section has been studied. All the samples display typical hat-shaped REE patterns, moderate negative Ce anomalies（Ce/Ce＊=0.55 to 0.67）, slightly positive Eu anomalies（Eu/Eu＊=1.05 to 1.22） and low Y/Ho ratios（38.2±5.6）. The hat-shaped REE patterns indicate diagenetic alteration of the primary REE signatures, which coincides with detrital siliciclastic sources of REE based on the Y/Ho ratios. The degree of Negative Ce anomalies and positive Eu anomalies may have recorded the redox features of diagenetic fluids, suggesting an anoxic environment during the phosphogenesis processes in Neoproterozoic Ediacaran Doushantuo Formation, South China. The geochemical comparison between the Lower Phosphorite Layer and Upper Phosphorite Layer at Hushan indicates a greater degree of diagenesis occurred in the Upper Layer than the Lower one. Besides the terrigenous sources of REE, organic materials could have also played a role on the REE characteristics.
