In short
In November 2015 I ordered the components for our offshore medical kit, meant to treat illness and injury where help may be more than 24 hours away, and sized for our four little kids. I'm not a doctor, but I've taken Wilderness Medicine and CPR courses. I used supply lists from the Adventure Medical Marine 3000 and OceanMedix kits, and added a Waterjel burn kit, a suture kit, Save-A-Tooth and child-sized SAM splints.
I’ve just ordered the components for our onboard medical kit. Building an offshore medical kit is not cheap. My goal was to be able to treat ailments and injuries offshore, where help might be more than 24 hours away. I also wanted a kit that was sized for our family. We have four little kids.
Most off-the-shelf medical kits are designed for adults. Medication strengths and ready-made splint sizes, for example, are different for children. Who wouldn’t want a cherry-flavored tongue depressor if there was one available?
I really enjoyed researching the components of our medical kit. My research took me to websites for off-the-shelf medical kits — from the cheapest imaginable to expensive, comprehensive professional kits.
I read web content from industry experts and doomsday preparedness folks. This self-sufficiency website will teach you how to staple skin by practicing with bedsheets, for example.
I should point out that I am not a doctor, dentist, or burn expert. But I have taken Wilderness Medicine and CPR courses. The purpose of this blog post is to share some of the resources that I discovered while researching the contents of our marine medical kit. Don’t sue me if you decide to buy a skin stapler and ruin a perfectly good bedsheet.
Resources for Building an Offshore Medical Kit
To build our medical kit, I used the supply lists of various off-the-shelf medical kits, including:
- Adventure Medical Marine 3000 First-Aid Kit (now replaced with the Marine 3500 Medical Kit )
- OceanMedix Prescription Medicine Kit (now replaced with Ocean Medic 911 OFFSHORE First aid Kit)
- Waterjel large soft-sided burn products
- Suture/Syringe Medic Single-Use First-Aid Kit by Adventure Medical Kit
The Adventure Medical Marine 3000 First-Aid Kit is organized into colorful, ailment-specific pouches. The supply list is detailed enough that I could order my own products online.
The OceanMedix Prescription Medicine Kit includes over-the-counter medications and prescription medications. The premise behind the prescription kit is described by OceanMedix co-founder Denny Emory, as follows:
…getting sick is far more common than getting injured. Six out of every 10 calls for medical consultation at sea result from illness rather than injury, according to the U.S. Coast Guard and offshore sailing organizations.
I’ve ordered virtually all of the over-the-counter medications online. The first of our over-the-counter medications arrived today as my husband awkwardly said, “Here’s your bottle of…” and trailed off as he abandoned our new bottle of stool softener on a counter.
The Waterjel Burn Kit may be overkill for our needs. But like the cautious mom that I am, I want to be prepared.
The Suture/Syringe Kit is there as a last resort if we need it. I don’t know how to suture or give injections. But I’d like to have my own supplies in case we need them at a hospital with limited resources.
Medical and First-Aid Resources We Found Useful
Our medical kit was further enhanced after reading the following websites:
- How to Make Your Own Dental First-Aid Kit
- Build Your Own First-Aid Kit, It Might Save Your Life (by Wes Siler, writer of Indefinitely Wild)
The dental website drew my attention to the Save-A-Tooth product. There’s probably a DIY method to store a tooth for up to 24 hours. But with sketchy internet access, and in a toothless panic, I shall defer to the dentist’s suggestion and just buy the product he recommends. I also learned that not all dental mirrors are created alike. Some use glass mirrors and others use cheap plastic.
Finally, Indefinitely Wild’s survival website suggested duct tape. Excellent. It was on this website that I first learned about SAM splints, including child-sized SAM splints.
I expect to complete our medical kit in the next two weeks as products arrive. I will also be building a separate medical kit for our ditch bag for our life raft. Following the modular layout of the Adventure Medical Marine 3000 First-Aid Kit, I plan to organize the contents by ailment and label absolutely everything.
The results of my research, planning, purchasing and a decade of experience sailing as a family is described in Offshore Medical Kit List: What We Used After 10 Years.
