The majority of cases with sig- nificant nerve damage either involve detainees who are intoxicated or have a clear history of excessive pressure being applied by the officers (5) generic dapoxetine 60 mg. Intoxica- tion may cause problems through a decreased awareness of local pain safe dapoxetine 60 mg, marked uncooperativeness buy 90mg dapoxetine with amex, or poor memory for the restraining episode when a signifi- cant struggle occurred. It is possible to have nerve damage with no skin break- age, reflecting undue pressure. Although some of the quoted studies predate the introduction of rigid handcuffs, because of the similar ratchet mechanism, direct pressure problems are still possible. Sensory nerve damage causes loss of pain, touch, and temperature sen- sation over an area of skin that is smaller than the nerve’s sensory supply because of the considerable overlap between the sensory territories of adja- cent peripheral nerves. Lesser degrees of damage lead to tingling, pain, and numbness in the appropriate sensory distribution. In acute compression of the nerve, symptoms appear more or less abruptly, and relief of this acute com- pression should lead to resolution in the course of some weeks. Associated motor weakness can be demonstrated by the correct clinical test within the hand. It should be noted that compression of the radial nerve at the wrist does not result in weakness. There was little formal training with these, but actual use was not that common, either because they were not terribly effective or the situations faced at that time could be dealt with differently. In 1993, trials of both side-handled and numerous straight batons were introduced, because there was a rise in the number of officers injured on duty and the adequacy of their equipment was called into question. Weighing approx 600 g with a shaft of polycarbonate plastic or aluminium, it has a fixed grip at right angles to the shaft toward one end. The addition of the handle to the shaft makes it versatile, with more than 30 blocking and striking techniques available to the officer. Correct use in stressful and challenging situ- ations requires extensive and ongoing training. It is carried unobtrusively on the belt and does not impede the general movement of the officer. This gives more weight distally, but it is prone to becoming flattened and rough over time because the baton is closed by striking this end against the ground. The acrylic patrol baton has a solid or hollow nylon shaft with a ring of rubber separating the shaft and handle. It is broader than the friction lock type and, therefore, less likely to cause injury because the imparted energy is spread over a larger area. The heavier weights of these types of batons are used in public order disturbances. In the United States, a 26-in hickory (wooden) straight baton is used (similar to group 3 in the previous list). The situation throughout the Austra- lian states is variable, with intrastate differences relating to specific police staff; for example, plain clothes staff may use an Asp-type baton, whereas uniformed officers are equipped with straight or side-handled batons. Strikes are made from an officer’s strong (dominant) or weak (nondominant) side, and clearly the potential for injury varies with the baton mass and velocity at impact, the target area, and to how much of the surface area the force is applied. Although no body area is absolutely forbidden to strike, an officer must use a proportionate response to the situation he or she faces knowing the potential to injure. Although target areas are divided into low-, medium-, and high-risk areas, maintaining a distinction between them can be difficult because strikes are made in dynamic situations where an initial target area may change as the potential detainee moves. Target areas with a low injury potential are the areas of the common peroneal, femoral, and tibial nerves on the legs and those of the radial and median nerves on the arms. There is a low probability of permanent injury, with the main effects being seen as short-lived motor nerve dysfunction, as in a “dead leg” and bruising. The medium injury potential areas involve bones and joints, including the knees and ankles, wrist, elbow, hands, upper arms, and clavicle. In these cases fractures, dislocations, and more extensive soft tissue injuries would be expected. Finally, those areas with the highest risk of injury include the head, neck and throat, spine, kidneys, and solar plexus. The most common injury is bruising, and this is often in the pattern of so-called “tramline bruising,” where two parallel lines of bruising are sepa- rated by a paler area. This is not unique to a baton injury but reflects an injury caused by any cylindrical hard object. The absence of bruising or other find- 200 Page ings does not mean that a baton was not used because, for example, a degree of cushioning can occur from clothing. It is possible for a detainee to have signs but minimal symptoms or even be unaware of being struck. Fractures need to be considered where there are the traditional clinical signs of local pain, swelling, and loss of function. Considering the forces that can be applied when necessary, there is the potential for significant injury with bruising and rupture of internal organs, including the heart, liver, spleen, or kidneys or a head injury. The forensic physician should refer suspected cases for hospital review without delay, es- pecially if a confirmatory history for events is unavailable. Particular care is needed in those who are intoxicated because they are difficult to assess. Because they cannot be released them- selves, snips to cut them are always available at the same time. Although quick and easy to apply, they have no way of being locked in position, so they can tighten in an uncontrolled manner, resulting in direct compression injuries. At least two ties are used on each detainee; one is placed on each wrist and then interlocked with the other. These plastic constraints are used in preplanned operations, where numerous arrests are expected or in special- ized operations. Excessive force, either directly applied by the officer or from a detainee continuing to move, can result in strains to joints, such as the wrist, elbow, and shoulder. Officers in the United Kingdom are not trained in any neck holds because of the high risk of serious injury or death as a result of large blood vessel or airway compression. Fatalities can occur quickly, and if a detainee complains of such holds being used, the neck should be examined carefully. Petechial bruising should be looked for in the face, particularly in and around the eyes, on the cheeks, and behind the ears. It is common for clothing to be held in a struggle to restrain, which may tighten it around the neck. Linear bruising Medical Issues of Restraint 201 may be seen at the site of tightening, as well as petechial bruising on the neck and above on the face. Clearly, the tactical firearms units are often required in these situations, but there is an increasing trend to look for other “nonlethal” options, which will incapacitate with a lower risk of serious injury. In the United Kingdom, the investigation of firearm inci- dents under the auspices of the Police Complaints Authority with its attendant recommendations is a major influence when looking at developments in this area (7). Different countries use different restraint equipment, such as water cannon or the firing of different projectiles (e. They were first introduced in Northern Ireland in 1970; 125,000 rounds have been fired, and 17 fatalities have resulted, the last one occurring in 1989.
