Goals in the care of the mechanically ventilated patient are sedation, analgesia, anxiolysis, and muscle relaxation. Causes of distress in these patients include: pain, sleep deprivation, anxiety, psychosis, agitation, and delirium. Drugs used to alleviate these stressors are opiates, benzodiazepines, neuromuscular blocking agents, anesthetic induction agents, and inhalational agents. When caring for the agitated patient on the mechanical ventilator, physiologic, mechanical, and emotional causes must all be investigated. Finally, nonpharmacologic therapy is of utmost importance in the care of these patients.
Our study showed 70%, 61.8%, and 56. 4% protection with Tecnu, Goop, and Dial, respectively, when compared to the positive control, or to the possible maximum response, with a cost per ounce (in a local drug and automotive store) of $1.25, $0.07, and $0.07, respectively, for a decrease in protection that is nonsignificant.
The objective of this study was to evaluate and assign numbers to biochemical or cellular entities in lung-healthy patients that change immediately postsurgery compared with the same parameters immediately presurgery, with the hypothesis that biochemical markers with significant change could be the basis of tests to predict postoperative respiratory complications. Thirty lung-healthy adults who were to undergo elective surgical procedures requiring general anesthesia participated. The population included sequential persons that met inclusion criteria and gave consent. At intubation and before surgery, a bonchoalveolar lavage (BAL) was performed. Before extubation but after completion of surgical procedures, a second 100-ml BAL was performed in the contralateral lung. Serum from both time periods was also collected. Total cell counts were elevated postsurgery in smokers and subjects claiming childhood but not current asthma, who also showed increased postsurgical BAL IL-1 but not increased TNFalpha. LDH and its isoenzymes, measured in both BAL and serum, showed no correlation with time on surgical ventilation, average FiO2, or average peak pressure during surgical ventilation. BAL LDH isoenzyme 4 showed a significant elevation pattern pre-to-post surgery when the entire subject population was considered irrespective of surgery type or time on ventilation. Presurgery versus postsurgery variation was best measured in BAL rather than in serum. The pulmonary, biochemical, and cellular parameters measured in the pre- and postsurgical BALs of lung-healthy subjects undergoing nonthoracic surgery show subtle modulations of pulmonary defense markers, defined by significantly increased proinflammatory cytokines and cell counts postsurgery compared to the same patient presurgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
