MARINE MEDICAL KITS
Michael Jacobs, MD
Following this presentation, participants will be able to:
1. Select appropriate medical supplies for a personal and ship’s medical kit.
2. Understand the specific use of these items.
Medical Care At Sea
Ask Dr. Bill Forgey, an expert in wilderness medicine, to identify the most important component of aback country snake bite kit, and he’ll quickly reply, “The car keys.” Ask Viktor Yazykov, a sailor whocircumnavigated the globe in the 1998-99 Around Alone Race, what he considers the most essential itemsin a marine medical kit, and he’ll certainly respond: “A satellite telephone and computer.” Indeed, hecould not have drained a potentially life-threatening abscess in his elbow without a detailed, 14-stepsurgical procedure e-mailed to him from physicians at WorldClinic, a medical practice that uses phones,satellites, and the Internet to treat patients around the globe.
On land, access to definitive medical care for a critically sick or injured person involves rapid transportto a medical facility, hence Forgey’s car keys. At sea, direct radio consultation with the medical facilitymay be the only way to obtain medical expertise; evacuation of crew may be too hazardous or impossi-ble. In the South Atlantic, a satellite phone was Yazykov’s best option.
Modem radio and satellite communications have fostered an over-dependence on search and rescue formariners in times of peril. Paradoxically, a call for help during a medical emergency may actually facilitateself-reliance and eliminate the necessity for evacuating the patient.
In order to treat a broad range of medical problems at sea, a cruising sailor needs to focus on three key ar-eas: basic medical skills, radio equipment for consultation, and appropriate medical supplies.
Basic Medical Skills
The boat’s medical officer should know how to treat common ailments as well as life threatening emer-gencies, and be able to stabilize a crewmember with traumatic injuries.
The medical officer must also be well trained in patient assessment so he can transmit a precise and de-tailed report of the patient’s medical condition when consultation with a medical advisory service is re-quired. These companies provide the mariner with 24/7 access to physicians trained in the art of remotemedical support (see list of telemedicine companies). Coastal cruisers therefore require at a minimum, aVHF radio, and offshore sailors need a single side band radio, satellite phone, or ham radio. Consider thisequipment an integral component of the medical kit.
The comprehensive list of medical supplies listed below is divided into two main groups: items that belong
in the crewmember’s kit
and those that belong in the ship’s primary medical kit
. Thoughtful selec-
tion of medical supplies involves consideration of the following factors and how they specifically relate
• Common ailments at sea. For example: sunburn, skin infections, and seasickness.
• Common onboard traumatic injuries. Sailors frequently suffer head, chest, and hand injuries.
• Number of crew and duration of trip. This determines the quantity of medications and supplies.
• Environmental extremes on the trip. Remember, suppositories melt and liquids freeze.
• Endemic diseases in cruising areas.
• Medical problems associated with specific activities in the aquatic environment e.g., scuba diving,
• Medical expertise of crew (surgical types love to stitch and start IVs; medical types favor glue and
• Access to reliable and comprehensive medical care.
Don’t expect to treat every medical or surgical emergency. However, don’t omit items simply becauseyou’re going on a short coastal trip. The same medical problems may occur on a weekend cruise ormonth long trip. Drugs and supplies useful for a variety of medical problems should be selected.
The Crewmember’s Medical Kit
Each crew member needs a personal kit. Alternatively, the ship may stock a conveniently accessiblecrew medical kit for a variety of simple and common medical problems. Keeping this kit separate ensuresthat supplies in the ship’s primary medical kit remain intact, organized and protected. Items should begrouped and packaged in zippered plastic freezer bags, and stored in a watertight container that floats.
The following is a list of suggested supplies and non prescription medications. Brand name drugs (in Ital-ics) can be substituted with other brands or less expensive generic preparations.
Seasickness Medication: Bonine, Dramamine,
ginger capsules or other remedies that work for you
and your crew. Add Sudafed
to counteract drowsiness from antihistamines.

for aches and pains: Ibuprofen (Motrin

), and enteric coated aspirin (Ecotrin
); acetaminophen (Tylenol
) for painrelief and fever. Many nonsteroidal anti-inflammatory drugs (NSAIDs) may increase sensitivityto the sun, so minimize sun exposure when using them,

for existing medical problems and anticipated complications; review with your
personal physician and the ship’s medical officer.
The Ship’s Primary Medical Kit
There are two categories of ship’s medical kits—coastal and offshore. Combined with the appropriatemarine radio or phone for consultation, the kit can be designated for use in either nearshore (coastal) oroffshore waters. The coastal medical kit is appropriate for cruising within the 20-mile range of a VHF ra-dio, a distance within which shore-base assistance will likely be able to evacuate the patient within 24hours. The coastal medical kit must have supplies to treat common problems as well as stabilize a moreseverely ill patient in the event that transfer to a hospital is delayed.
The offshore cruiser, with SSB (single-sideband) radio or satellite phone should be prepared to delivermore comprehensive and longer-term treatment. Professional medical care may be days to weeks away,or not available at all, and someone on board may have to provide definitive treatment.
In the list below, an asterisk * denotes drugs or items that are optional for the coastal kit but necessaryin the offshore kit.
The following medications require a prescription. They have been selected because they are easy to ad-minister, have convenient dose schedules, show little to no incidence of sun sensitivity reactions, and areeffective for a broad spectrum of applications for the sick crewmate.

Several items have not been recommended for the offshore kit for the following reasons:
• Intravenous solutions and supplies for administering them are of limited value to the untrained per-
son, but trained medical professionals may consider adding them.
• Automatic external defibrillators are life-saving only if expert intensive care together with a full
complement of drugs and equipment is immediately available. Non-fatal heart attacks can betreated with aspirin, oral and topical nitrates, and beta-blockers.
Medications and antibiotics may cause serious adverse reactions, so review the suggested list of drugswith your physician to better understand the Indications for use, side effects, and dose schedules. Stockalternative drugs If crew have known allergies to specific medications. Update and replace pharmaceuti-cals in the kit according to expiration dates. Use extreme caution when administering drugs to Infants,small children, pregnant women, and nursing mothers. When a medical problem arises, it’s always best toconsult a physician or nurse practitioner to review the diagnosis and appropriate therapy.
