Nursing implications

Nursing assessment

  • Assess for infection (vital signs; appearance of wound, sputum, urine, and stool; WBC) at beginning of and throughout therapy.
  • Obtain specimens for culture and sensitivity before initiating therapy. 1st dose may be given before receiving results.
  • Before initiating therapy, obtain a history of tetracycline hypersensitivity; may also have an allergic response to tigecycline.
  • Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of pseudomembranous colitis. May begin up to several weeks following cessation of therapy.
  • Assess patient for signs of pancreatitis (nausea, vomiting, abdominal pain, increased serum lipase or amylase) periodically during therapy. May require discontinuation of therapy.
  • Assess for rash periodically during therapy. May cause Stevens-Johnson syndrome. Discontinue therapy if severe or if accompanied with fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, hepatitis and/or eosinophilia.
  • Lab Test Considerations: May cause anemia, leukocytosis, and thrombocythemia.
    • May cause ↑ serum alkaline phosphatase, amylase, bilirubin, LDH, AST, and ALT.
    • May cause hyperglycemia, hypokalemia, hypoproteinemia, hypocalcemia, hyponatremia, and ↑ BUN level.

Patient/Family Teaching

  • Advise patient that full course of therapy should be completed, even if feeling better. Skipping doses or not completing full course of therapy may result in decreased effectiveness and increased risk of bacterial resistance.
  • Instruct patient to notify health care professional if fever and diarrhea develop, especially if stool contains blood, pus, or mucus. Advise patient not to treat diarrhea without consulting health care professional.
  • Advise patient to report the signs of superinfection (black, furry overgrowth on the tongue, vaginal itching or discharge, loose or foul-smelling stools). Skin rash, pruritus, and urticaria should also be reported.
  • Advise female patient to use a nonhormonal method of contraception while taking tigecycline and until next menstrual period.

To assess the susceptibility pattern of MRSA against vancomycin, linezolid, tigecycline, rifampicin, fosfomycin fusidic acid, clindamycin, trimethoprim-sulfamethoxazole and teicoplanin, minimum inhibitory concentrations (MICs) for given antimicrobials were performed on 234 MRSA clinical isolates using automated VITEK 2 system.
Therapeutic regimens were chosen based on local epidemiology, with suggestions avoiding the use of linezolid, daptomycin, tigecycline, and carbapenems, due to the high cost.
