All devitalised muscle must be removed; if not the chance of infection is greater. It is better to take good muscle and have some deformity, than to leave devitalised muscle and have infection. The preferred method for debridement is to cut along one side of a muscle group in strips or blocks and not piecemeal a. Remove all blood clots, foreign material, and debris from the wound during exploration of the wound with a gloved finger. Vital structures like major blood vessels and nerves must be protected from damage. All foreign bodies must be removed, including small detached bone fragments, but time must no be wasted looking for elusive metallic fragments which would require more extensive dissection. Repeated irrigation of the wound with physiological salt solution during the operation will keep the wound clean and free of foreign material. When debridement is complete, all blood vessels, nerves, and tendons should be covered with soft tissue to protect from drying out. Dependent drainage of deep wounds must be employed << Place a Penrose drain (rubber tube) or wicking gauze into the wound>>. Liberal fasciotomy of an extremity is often an additional precaution that allows for post operative swelling. Use when the 5 P are present distal to a limb injury – pain, pallor, pulselessness, puffiness or paraesthesia - 172 - Survival and Austere Medicine: An Introduction m. Do not dress the wound with an occlusive dressing, but place a few strips of fine-mesh gauze between the walls of the wound, placed puffed gauze in the pocket formed and then dress the wound to protect, but not constrict. All wounds should be left open with the exception of wounds of the face, sucking chest wounds, head wounds, wound of the joints or synovial membranes, and wounds of the peritoneum o. Immobilisation and correct positioning of the injured part promotes healing, and these measures should be used even of no fracture is present. As we have said frequently here, if you attempt the things described here without the appropriate knowledge you will kill people. The standard technique of giving fluids to an unconscious, shocked, or dehydrated person is with intravenous fluids. This method will obviously not work if the cause of the problem is severe diarrhoea. A lubricated plastic tube with a blunt end (a large urinary catheter or nasogastric tube is ideal) should be passed through the anus into the rectum for about 9 inches. A longer length of tubing and a drip bag or funnel should be attached to the end and elevated. If 200 ml is tolerated it can be worth increasing the volume slightly or reducing the time to 3 1/2 or 3 hrs. A rectum full of faeces does not absorb water very well, so the amounts may need to be reduced, but given more frequently. Amputation was one of the most common surgical procedures of the last two centuries – life threatening infection from wounds and compound fractures were common, and in the absence of antibiotics amputation was the only option. Amputation in an austere situation needs to be viewed as something only performed to save a life. All attempts should be made to save the knee and elbow joints even if this means having a short stump. Extremities with severe involvement of the skin, muscle, and bone with anaesthetic terminus or irreparable nerve injury c. Under combat conditions the most acceptable form of amputation is the open circular technique 1. A circumferential incision is made through the skin and deep fascia at the lowest viable level.

They are idealistic, and most come to medicine because they are inspired to contribute Emotional and physical fatigue lead to behavioural changes. Decreased interest in activities that were once enjoyed during free time leads to social withdrawal and personal isolation. However, the profession of medicine is demanding, and it is Relationships with family and friends are compromised, and diffcult to put limits around its practice. Poor constant exposure to suffering, heavy workloads, long hours, coping strategies that are adopted might include the increased time pressures, physical and mental demands, and a lack of intake of caffeine and alcohol, or the use of illicit drugs. Physicians are acutely Faced with some or all of these effects, one might experience aware of the distress of others but are often less attentive to at the same time a reduced sense of accomplishment and the stress and fatigue that they experience themselves. It is easy to lose sight of one’s accomplishments caring for others often leads to neglect of oneself. This is the sign of We know that physicians, as a group, are well informed with signifcant stress. We also know that when physicians are overwhelmed by the demands Given that the demands of the profession are ever present, of their profession, they are vulnerable to neglecting those what is the solution? It requires, frst and foremost, awareness of the risks mises not only the physician’s health, but his or her ability to that will be present and deliberate attention to measures of continue to provide care for others. Physicians’ self-care presents a perfect opportunity to practise preventative care. When self-care is neglected When a physician becomes immersed in his or her work to the Solutions: Think “self-care” exclusion of self-care, a cascade of stress-induced symptoms In The 7 Habits of Highly Effective People, Steven R.

The physician may become Balanced Self-Renewal,” which he describes as “preserving and prone to emotional outbursts, or may be tearful at work in enhancing the greatest asset you have–you. He or she may take domains that require attention in self-care: physical, emotional, less pleasure in activities that were once much enjoyed. Effective self-care requires consideration meantime, a denial of the signifcance of these symptoms and of these four domains, and taking control of the things that the vulnerability they reveal can lead the physician to take on can be controlled.

Therefore, take the tops of elder and grind them and, having extracted the juice, mix with barley flour and with the white of an egg, and then make little wafers with suet for eating. On the Preservation of Celibate Women and Widows [] There are some women to whom carnal intercourse is not permitted, sometimes because they are bound by a vow, sometimes because they are bound by religion, sometimes because they are widows, because to some women it is not permitted to take fruitful vows. Take some cotton and musk or penny- royal oil and anoint it and put it in the vagina. And if you do not have such an oil, take trifera magna6 and dissolve it in a little warm wine, and with cotton or damp wool place it in the vagina. Note that a pessary ought not be made lest the womb be damaged, for the mouth of the womb is joined to the vagina, like the lips to the mouth, unless, of course, conception occurs, for then the womb withdraws. But because some women are fat, as though they had dropsy, and some women thin, both the former and the latter are incapable of conceiving. If she is phlegmatic and fat,7 we should make her a bath of seawater, moderately salty, with rainwater. In this bath she should stay until she sweats sufficiently; afterward let her be received in bed carefully and let her be well covered. Thus let there be made for her a bath three or four times that day, and likewise the following day. On the third day, let there be a very good, strong-smelling fumigation, as we described above.

Then let her enter a steambath up to the neck, which steambath should be very hot from a fire made of elder [wood], and in it, while she is covered, let her emit a lot of sweat, and as though in a sweat bath let her remain there until she has purged herself a little through the inferior members, and that which comes out will be rather greenish. After she has thoroughly sweated, let her wash herself with the water of the previous bath, and thus let her cautiously enter her bed. And let this be done twice or three times or four times a week, and she will be found to be sufficiently thin. We make for them a grave next to the shore of the sea in the sand, and in the described manner you will anoint them, and when the heat is very great we place them halfway into the grave, halfway covered with hot sand poured over. On Extracting the Dead Fetus [] Those who labor excessively in giving birth to a dead fetus we assist thus. Let us place the patient on a linen sheet and let us have it held by four strong men at the four corners, the head of the patient a little bit elevated. We will make the sheet be pulled strongly this way and that at the opposite corners, and immediately she will give birth. On Retention of the Afterbirth [] There are some women to whom the afterbirth remains inside after birth, to whom we give aid for its expulsion thus. Extrahamusb succum arthimesie, saluie, pulegii, per- siccarie, et aliarum herbarum huiusmodi, et faciamusc crispellas et demusd ad comedendum, et collocemuse eas frequenterf in balneis,g et predicto modo ad restringendumh sanguinem subuenimus.

On Excessive Flow of Blood After Birth [] There are other women who after birth have an immoderate flow of blood, to whom we give aid thus.
