Warning Warning!

I would be very interested in knowing the title and author of the book you are reading - sounds like it may be full of helpful information - just as Dilbert should be read by all managers.

Not all things written books make sense and not all books are written by intelligent people!

As has already been noted - safety pinning someone tongue to their lip is utter nonsense! If you have a patient that is numb enough to allow you to do that without kicking you in the head then you are far better off using an oral airway or a NP airway. Both of these can be had in adjustable versions and the NP airway (nose-hose) is flexible and fairly easily packed and even rather well tolerated should the individual awake after you inserted it. Of course you shouldn't be using these items without the proper training and the NP airway is strongly contra-indicated in the case of a head injury that may have damaged the palate.

suturing a wound in the field is also a bad idea. It is almost impossible to get the wound properly cleansed in the field such that if you close it you won't be sealing in an infection which may lead to gangrene. The heavy bleading should be manageable if it is not arterial. The healing process will begin without closing and the only real difference between closing and not closing the wound is the area of scar tissue resulting. - leave it open, irrigate with sterile water (which can be had by boiling easily enough) twice daily keep wrapped in sterile dressings == boiled bandannas at minimum and immobilize as necessary depending upon the severity. Don't use unsterile thread to close a deep wound in the field or you will be using your jack-knife to amputate in a few short days in order to prevent the gangrene from migrating into the vitals.
