Pathogenesis, optical phenomenon and risk factors, diagnosis, administration, and prevention of postoperative and ventilator-associated pneumonia are described.ATS/IDSA Recommendations for Treating Ventilator-Associated Pneumonia
In 2005, the English Thoracic Club and the Infectious Diseases Lodge of US published consensus recommendations that outlined an evidence-based scheme for initiating antimicrobial therapy in patients with suspected ventilator-associated pneumonia (VAP). Patients with early-onset postoperative pneumonia or VAP who have no risk factors for multidrug-resistant pathogens may be treated with ceftriaxone, a quinolone (cipro, levofloxacin, or moxifloxacin), ampicillin-sulbactam, or ertapenem.
In demarcation, patients with late-onset postoperative pneumonia or VAP and those with risk factors for multidrug-resistant organisms must be treated more aggressively.
They should be started on mathematical process therapy for gram-negative infections and should receive agents that provide broad insurance coverage of gram-positive infections (see Array 1 ).
Vancomycin or Linezolid for VAP?
Two prospective, randomized, multicenter trials compared vancomycin with linezolid for the intervention of nosocomial pneumonia.
The two agents were found to have similar clinical cure rates and microbiologic attainment rates in all of the patients studied, suggesting that these agents are equally effective in the typical participant role with gram-positive nosocomial pneumonia. Two retrospective analyses pooled patients from these two trials in a subset of patients with methicillin-resistant Staphylococcus aureus (MRSA) nosocomial pneumonia and in a smaller subset comprising patients with VAP from MRSA. Both analyses demonstrated significantly improved aliveness and clinical cure rates in patients treated with linezolid.
In the 160 patients with MRSA nosocomial pneumonia, attention with linezolid was associated with an modification in the Kaplan-Meier action rate from 63.5% to 80.0% and an modification in the clinical cure rate from 35.5% to 59.0%. In the 91 patients with VAP from MRSA, logistic defense reasoning showed that attention with linezolid was an self-employed person information of continuation (odds magnitude relation, 4.6) and clinical cure (odds magnitude relation, 20.0).
In ambit, a written report comparing vancomycin with quinupristin-dalfopristin found the two drugs to have similar cure rates both in nosocomial pneumonia patients as a object and in a subset of patients with MRSA pneumonia. Although the favorable linezolid results are obviously limited by the fact that they derive from retrospective analyses of data pooled from two studies, they do acclivity the uncertainty of whether linezolid should be the antibiotic of pick in patients with MRSA pneumonia.
If vancomycin is used to victuals MRSA, it should be given in an initial dose of 15 mg/kg, and gutter levels should be maintained between 15 and 20 µg/ml. Rotating Antibiotics to Reduce Capacity
Scheduled revolution of antibiotics on a code of conduct part has been proposed as a proficiency for hindering the growth of resistant organisms in patients with VAP by manipulating prevailing antibiotic pressures in the health facility surround. Antibiotic transformation has been studied in both surgical ICUs and surgical wards.
A subject area of 1,456 patients in a surgical ICU compared infection-related mortality rate during a 1-year time expelling without an antibiotic code of conduct with infection-related deathrate during a 1-year division in which antibiotics were rotated on a quarterly assumption. Antibiotic chronological succession reduced infection-related rate from 9.6 to 2.9 deaths per 100 admissions; in summation, it reduced the rates of resistant gram-positive coccus illegality (from 14.6 to 7.8 infections per 100 admissions) and resistant gram-negative bacillus pathologic process (from 7.7 to 2.5 infections per 100 admissions).
A follow-up musical composition examined 2,088 patients both in a surgical ICU and in the ward they were transferred to, using a room purpose in which ICU patients (but not structure patients) were treated for 1 year without an antibiotic gyration etiquette and for 1 year with such a code of conduct. In the rank someone of the year, patients received ciprofloxacin with or without clindamycin for pneumonia; in the mo, piperacillin-tazobactam; in the position, carbapenem; and in the musical interval, cefepime with or without clindamycin.
The survey demonstrated that the coverall definite quantity of hospital-acquired infections was decreased on the surgical ward in the year that antibiotic motility was instituted in the ICU.
Similarly, the frequency of resistant gram-positive and resistant gram-negative infections was reduced on the surgical ward when antibiotic succession was practiced in the ICU.
