What You Need to Know Before You Apply

What is the purpose of this trial?

Antibiotics are sometimes prescribed to patients who have had reconstructive surgery of wounds on their face using skin grafts. But, it is not yet known whether antibiotics improve the healing of skin grafts and reduce the risk of infections after surgery in these patients. It is known that antibiotics, like all medications, have side-effects although these are rare. This research study is designed to show us whether antibiotics improve wound healing or not, so that we may determine if we should continue using antibiotics even if they have side-effects in some patients. Our hypothesis is that patients treated with post-operative, systemic antibiotics will demonstrate a statistically significant improvement in the survival of their facial full thickness skin grafts compared to patients who are not treated with systemic antibiotics.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you have used systemic antibiotics within one week before surgery.

Is cephalexin safe for use in humans?

Cephalexin, a type of antibiotic, is generally safe for treating skin and soft tissue infections, with common side effects being mild skin reactions and stomach issues. In studies, only about 5% of patients stopped using it due to side effects, indicating it is well-tolerated by most people. ^{1 2 3 4 5}

How does the drug used in the clinical trial for facial reconstructive surgery differ from other treatments?

The antibiotics used in the trial, such as ceftriaxone, are unique because they can be administered as a single daily dose due to their long half-life, making them more convenient and cost-effective compared to other antibiotics like cefotaxime, which require more frequent dosing. ^{6 7 8 9 10}

What data supports the effectiveness of the drug cephalexin for facial reconstructive surgery?

Cephalexin is effective in treating skin and soft-tissue infections, achieving cure rates of 90% or higher, which suggests it could be beneficial in preventing infections after facial reconstructive surgery. Additionally, in a study on endoscopic skull base surgery, a regimen including cephalexin showed low rates of postoperative infections, supporting its use in surgical settings. ^{6 7 8 11 12}

What Are the Treatments Tested in This Trial?

Interventions

• Cephalexin

Trial Overview The study tests if post-operative antibiotics (cephalexin) improve the healing of facial skin grafts compared to not using them. The goal is to see if antibiotics should be used despite potential side effects.

How Is the Trial Designed?

Group I: Antibiotics Experimental Treatment 1 Intervention

All patients will receive peri-operative antibiotics per standard practice. This consists of a single dose of cefazolin or, in penicillin allergic patients, clindamycin administered at the time of anesthesia administration prior to the surgical incision. In the cohort randomized to receive post-operative antibiotics, the first choice intervention will be oral cephalexin (500 mg, three times daily or four times daily, for one week). In patients who are penicillin or cephalosporin allergic, we will prescribe clindamycin (300 mg, three times daily or four times daily, for one week).

Group II: No antibiotic treatment Active Control 1 Intervention

Withholding post-operative antibiotics following reconstructive surgery necessitating skin grafting for defects of the face or nose.

Published Research Related to This Trial

In a study of 60 patients undergoing cervicofacial surgery, both cefotaxime and ceftriaxone were effective as short-term prophylactic antibiotics, with only one postoperative infection observed.

Ceftriaxone is advantageous due to its longer half-life, allowing for a single daily dose, and it is also more cost-effective compared to cefotaxime.

Cephalexin is a highly effective antibiotic for treating streptococcal and staphylococcal skin infections, achieving cure rates of 90% or higher over 12 years of use.

It is well-absorbed and bioavailable, with a twice-daily dosage that improves patient compliance, and its mild side effects make it suitable for young children.

In a study involving 350 patients, the use of single intravenous injections of antibiotics (Ceftriaxon, Rocifen, Lyncomycin) before surgery effectively prevented postoperative purulent complications in closed mandibular fractures and reconstructive maxillo-facial operations.

The antibiotics also significantly reduced the frequency of complications in cases of open fractures of the mandible and nasal bones, highlighting their efficacy in maxillo-facial surgery.

In a study of 132 patients undergoing endoscopic endonasal transsphenoidal surgery, a standardized antibiotic regimen of cefazolin followed by cephalexin resulted in low rates of postoperative infections, with only 4% developing sinusitis and 3% pneumonia.

The study found that despite a high rate of intraoperative cerebrospinal fluid leaks (40%), there were no cases of meningitis, indicating the efficacy and safety of the 7-day antibiotic protocol in preventing serious infections.

In a study of 44 patients undergoing mandibular surgery, oral levofloxacin demonstrated a high efficacy rate of 95% for preventing postoperative infections, comparable to the 85.7% efficacy of intravenous cefazolin sodium.

Levofloxacin achieved effective concentrations in both serum and mandibular bone marrow, suggesting it is a safe and cost-effective alternative to intravenous antibiotics for this type of surgery.

Acute rhinosinusitis is a leading cause of antibiotic prescriptions globally, raising concerns about antibiotic resistance and the safety of commonly used antibiotics like macrolides and fluoroquinolones.

A surveillance study on the new cephalosporin drug Spectracef (Cefditoren) showed promising efficacy and safety for treating acute bacterial rhinosinusitis, particularly due to its different chemical structure that may reduce the risk of cross-allergy with penicillins.

In two randomized studies involving 343 patients, cephalexin hydrochloride was found to be as effective as cephalexin monohydrate for treating skin and soft tissue infections, with high response rates of 95.7% and 96.5% respectively.

Both formulations demonstrated a similar safety profile, with only 4.95% of patients experiencing adverse events, indicating that cephalexin hydrochloride is a safe and effective option for these infections.

In a study of over 6 million individuals, new penicillin allergies were reported more frequently after parenteral exposure (0.85%) compared to oral exposure (0.74%), indicating a higher risk of allergic reactions with injectable forms.

Anaphylaxis was rare, with only 22 cases associated with oral penicillin and 3 with parenteral penicillin, suggesting that while allergic reactions can occur, they are infrequent. Additionally, Clostridioides difficile infections were more common after parenteral antibiotic use, highlighting a potential safety concern with these treatments.

Third generation cephalosporins are a safe class of antibiotics with fewer side effects and lower allergenic potential compared to other antibiotics like penicillins and aminoglycosides, making them suitable for use in various healthcare settings.

While generally safe, some third generation cephalosporins can cause specific issues such as hypoprothrombinemia and disulfiram-like reactions, and they may lead to increased diarrhea and risk of drug-resistant bacteria if not monitored properly.

Cefazolin (Ancef) is a first-generation cephalosporin antibiotic commonly used in surgeries to prevent bacterial infections, and it is generally considered safe for most patients.

Despite concerns about cross-reactivity with penicillin allergies, the article aims to investigate the safety of cefazolin for patients with such allergies, suggesting that it may be a viable option rather than using less effective alternatives.

A single intravenous dose of ceftriaxone (1 or 2 g) administered one hour before elective surgery was highly effective, achieving a therapeutic success rate of 92% in a study of 100 surgical patients.

This study supports the use of ceftriaxone as a short-term antimicrobial prophylaxis to prevent infections in surgical patients, highlighting its efficacy in a clinical setting.

Cephalexin, a new antibiotic related to cephaloglycin, shows excellent oral absorption and minimal serum binding, which enhances its effectiveness despite lower in vitro antimicrobial activity compared to cephaloglycin.

In experimental studies with mice, cephalexin demonstrated exceptional efficacy against bacterial infections, outperforming other antibiotics like tetracycline and chloramphenicol, indicating its potential for clinical use.
