Although the majority of potentially preventable fatalities among U.S. combat forces serving in Afghanistan and Iraq have died from hemorrhagic shock, the majority of U.S. medics carry morphine autoinjectors for prehospital battlefield analgesia. Morphine given intramuscularly has a delayed onset of action and, like all opioids, may worsen hemorrhagic shock. Additionally, on a recent assessment of prehospital care in Afghanistan, combat medical personnel noted that Tactical Combat Casualty Care (TCCC) battlefield analgesia recommendations need to be simplified--there are too many options and not enough clear guidance on which medication to use in specific situations. They also reported that ketamine is presently being used as a battlefield analgesic by some medics in theater with good results. This report proposes that battlefield analgesia be achieved using one or more of three options: (1) the meloxicam and Tylenol in the TCCC Combat Pill Pack for casualties with relatively minor pain who are still able to function as effective combatants; (2) oral transmucosal fentanyl citrate (OTFC) for casualties who have moderate to severe pain, but who are not in hemorrhagic shock or respiratory distress and are not at significant risk for developing either condition; or (3) ketamine for casualties who have moderate to severe pain but who are in hemorrhagic shock or respiratory distress or are at significant risk for developing either condition. Ketamine may also be used to increase analgesic effect for casualties who have previously been given opioids (morphine or fentanyl.).

Surgical castration in male piglets is painful and methods that reduce this pain are requested. This study evaluated the effect of local anaesthesia and analgesia on vocal, physiological and behavioural responses during and after castration. A second purpose was to evaluate if herdsmen can effectively administer anaesthesia.. Four male piglets in each of 141 litters in five herds were randomly assigned to one of four treatments: castration without local anaesthesia or analgesia (C, controls), analgesia (M, meloxicam), local anaesthesia (L, lidocaine), or both local anaesthesia and analgesia (LM). Lidocaine (L, LM) was injected at least three minutes before castration and meloxicam (M, LM) was injected after castration. During castration, vocalisation was measured and resistance movements judged. Behaviour observations were carried out on the castration day and the following day. The day after castration, castration wounds were ranked, ear and skin temperature was measured, and blood samples were collected for analysis of acute phase protein Serum Amyloid A concentration (SAA). Piglets were weighed on the castration day and at three weeks of age. Sickness treatments and mortality were recorded until three weeks of age.. Piglets castrated with lidocaine produced calls with lower intensity (p < 0.001) and less resistance movements (p < 0.001) during castration. Piglets that were given meloxicam displayed less pain-related behaviour (huddled up, spasms, rump-scratching, stiffness and prostrated) on both the castration day (p = 0.06, n.s.) and the following day (p = 0.02). Controls had less swollen wounds compared to piglets assigned to treatments M, L and LM (p < 0.001). The proportion of piglets with high SAA concentration (over threshold values 200, 400 mg/l) was higher (p = 0.005; p = 0.05) for C + L compared to M + LM. Ear temperature was higher (p < 0.01) for controls compared to L and LM. There were no significant treatment effects for skin temperature, weight gain, sickness treatments or mortality.. The study concludes that lidocaine reduced pain during castration and that meloxicam reduced pain after castration. The study also concludes that the herdsmen were able to administer local anaesthesia effectively.
