Pain is a disastrous manifestation of cancer that influences the patients’ quality of life, their fami-lies, and health care providers. It is a multidimensional symptom that includes the physical, psycho-social, emotional and spiritual character of the human organism. Despite the development of new analgesic drugs and updated guidelines, the pain management remains insufficient, and some pa-tients with mild to severe pain do not received adequate pain treatment. This insufficient manage-ment can be attributed to barriers related to health professionals, to the patients, and the health care system. Common professional barriers include the bad pain evaluation, the lack of knowledge and skills, and the doctors’ reluctance to prescribe opioids. The barriers related to the patient include cognitive factors, emotional factors, and the compliance with analgesic regimens. Barriers related to the health system, like the limited access to opioids, and limited availability of pain and palliative care experts, consist additional challenges, especially in poor countries. Given the multidimensional nature of cancer pain, and the multilevelbarriers involved, the effective pain management demands multimodal interventions from interscientific groups. Educational interventions to the patients and health professionals it is possible to improve the successof pain management.

The occurrence of intraoperative oxygenation impairment is common even in healthy individuals and will vary depending on the patient and the type of surgery. The purpose of this study was to evaluate the incidence of oxygenation impairment in patients with normal lung function and to study the safety and efficacy of three different recruitment strategies. Out of a total number of 430 patients, 150 patients developed intraoperative oxygenation impairment, which was defined as the drop of PaO2/FiO2 ratio below 300. These 150 patients were randomly assigned into four study groups according to the recruitment strategy applied. Group A (N: 38): Application of three hyperinflations of the lungs at airway pressure 40cmH2O for 10 sec, followed by an increase in PEEP from 5 to 10cmH2O. Group B (N: 38): Increase in PEEP from 5 to 10cmH2O. Group C (N: 37): Application of three hyperinflations of the lungs at airway pressure 40cmH2O for 10 sec, without any PEEP alteration and Group D (N: 37): No maneuver. Measurements were taken at the phase of oxygenation deterioration and at 5, 15, 30, 45 and 60min after applying the maneuvers and also before extubation. From a total of 430 patients 150 developed oxygenation impairment (38.4%). The median onset time of the deterioration was 30min after intubation and mechanical ventilation. In group A the PaO2/FiO2 ratio increased significantly immediately after the maneuvers and remained elevated until extubation. In group B the PaO2/FiO2 ratio presented a gradual increase to significant levels before extubation. In group C, the instant post-maneuver increase of oxygenation was not sustained until extubation. Finally in group D a gradual decrease of the PaO2/FiO2 ratio was recorded until the end of surgery. According to the results of our study, one third of patients developed intraoperative oxygenation impairment approximately half an hour after intubation. The application of three hyperinflations of the lungs at an airway pressure of 40cmH2O for 10 sec, followed by an increase in PEEP from 5 to 10cmH2O proved to be the most effective treatment of impaired oxygenation.

The objective of postoperative pain management after thoracotomy is the prevention of postoperative complications, the reduction of the length of hospital stay, the increase of the patient’s satisfaction and finally the resumption of the daily living’s normal activities. Thoracic surgery affects postoperative respiratory function, along with a high risk of developing postoperative pulmonary complications. Pain is a subjective experience. Postoperative pain management in thoracic surgery patients should be individually applied, based on a well-organized health care system that emphasizes consistent nursing education regarding proper pain management techniques, with an effective communication between the patient and members of the existing multidisciplinary team, especially the nursing staff.
