DAN Medics and Researchers Answer Your Dive Medicine Questions
Q: On the day before my flight for a liveaboard dive trip, I slipped on some steps and got a laceration that took 14 stitches to close. Given the flight time and the liveaboard cruising time, it will be four days from the time of the accident to the time of the first dive. Is it safe to dive with a recently sutured wound?
A: No, it is not advisable to dive with a recently sutured wound. A laceration that required sutures represents a significant break in the skin’s protective barrier.
Sutures hold the wound edges together while the body goes through the early stages of healing, which include inflammation, tissue repair, and the gradual reestablishment of a protective skin layer. The wound remains vulnerable during this period, which is typically the first several days to weeks, depending on the wound location and severity.
Submerging a recently sutured wound in seawater poses several important risks. First, infection is a major concern. Seawater contains a wide variety of microorganisms, including bacteria capable of causing serious skin and soft-tissue infections.
Some marine bacteria can cause rapidly progressing infections that may require urgent medical treatment. The risk is even higher in warm, tropical environments, where bacterial concentrations are greater and infections can develop more quickly.
Second, mechanical stress can compromise the wound closure. Diving involves movement, exposure to equipment, and frequent contact with ladders, decks, wetsuits, and buoyancy gear. These forces can place tension on the sutures, potentially causing the wound to reopen — a process known as wound dehiscence. Even minor trauma or repeated rubbing against equipment may disrupt the healing process.
Third, the dive environment itself can delay proper care. Many dive trips, especially liveaboard expeditions or trips to remote locations, occur far from advanced medical facilities. If a wound becomes infected or reopens while at sea, appropriate treatment may be delayed, increasing the risk of complications.
For these reasons, the safest recommendation is to delay diving until the wound has adequately healed — long after the sutures have been removed — and until a health care professional confirms that the wound has closed sufficiently to tolerate water exposure. Depending on the injury’s location and severity, sutures typically remain in place for seven to 14 days or longer. Full healing may take additional time.
It is understandable that divers may be reluctant to postpone a long-planned trip, especially when travel and liveaboard logistics are involved. Diving is a recreational activity, however, and protecting your health should take priority over a scheduled dive itinerary. A serious infection or wound complication could not only jeopardize your health but also disrupt the trip for others.
If you sustain a wound requiring sutures before a dive trip, it’s best to consult with your treating physician and delay diving until the wound has healed sufficiently. Taking the time to properly recover greatly reduces the risk of infection and helps ensure you can safely enjoy diving again soon.
