Background: There are a number of factors relating to the host, bacteria an
d wound that are important in the development of wound infection. The effec
t of the surgeon sweating has not been previously reported.
Methods: Ten surgeons performed a mock total hip joint operation under ster
ile conditions while not sweating and then repeated the operation while swe
ating. Settle plates were used to quantify the bacterial counts in the oper
ative field in both phases.
Results: For each subject a mean of 3.3 colony forming units (c.f.u.) were
present in the non-sweating phase and 6.9 c.f.u. were present in the sweati
ng phase (P < 0.05). Organisms grown were normal skin flora.
Conclusion: The sweating surgeon may be more likely to contaminate the surg
ical field than the non-sweating surgeon. It is important for orthopaedic s
urgeons, especially those performing joint replacement surgery, to be aware
of this and to take measures to minimize sweating in the operating theatre
.
