Needlestick injuries are known to occur frequently in healthcare settings and can be serious. In North America, millions of healthcare workers use needles in their daily work, and hence, the risk of needlestick injuries is always a concern. While the introduction of universal precautions and safety conscious needle designs has led to a decline in needlestick injuries, they continue to be reported, albeit on a much smaller scale than in the past. Awareness of needlestick injuries started to develop soon after the identification of HIV in the early 1980s. However, today the major concern after a needlestick injury is not HIV but hepatitis B or hepatitis C. Guidelines have been established to help healthcare institutions manage needlestick injuries and when to initiate post-exposure HIV prophylaxis. The Centers for Disease Control and Prevention (CDC) has developed a model which helps healthcare professionals know when to start antiretroviral therapy. Needlestick injuries are an occupational hazard for millions of healthcare workers. Even though universal guidelines have decreased the risks of needlestick injuries over the past 30 years, these injuries continue to occur, albeit at a much lower rate. Healthcare professionals at the highest risk for needlestick injuries are surgeons, emergency room workers, laboratory room professionals, and nurses. The use of needles is unavoidable in healthcare, and even though every hospital has guidelines on proper handling and disposal of needles and the newest design of safety conscious needles, needlestick injuries continue to occur more often in et al. healthcare professionals like surgeons and emergency room personnel. In most cases, needlestick injuries occur chiefly because of unsafe practices and gross negligence on the part of the healthcare workers. The reality is that most needlestick injuries are preventable by following established procedures. Needlestick injuries came to the forefront of healthcare after the discovery of the HV in the early 1980s. Since the adoption of universal precautions, the number of needlestick injuries has greatly decreased but continues to occur, but the numbers are low. Today the major threat after a needlestick injury is not HIV but acquiring hepatitis B or hepatitis C. In the past, the majority of needlestick injuries occurred during resheathing of the needle after the withdrawal of blood from a patient. Even though this practice is now no longer recommended, there are experts in infectious disease who indicate that not resheathing the needle greatly increases the risk of needlestick injuries in house cleaners and porters who are in charge of collecting and disposing of the sharps containers. Over the years, many cases of cleaners and porters being injured by unsheathed needles have been reported. Further, this is more of a concern when healthcare workers ignore policies and discard needles directly into the plastic bags instead of the sharps containers. To prevent these injuries, many healthcare institutions have now adopted unique ways of resheathing needles. For example, in the operating room, there are now established protocols on how the nurse will pass sharp instruments and needles to the surgeon and vice versa. Another method of avoiding needlestick injuries is double gloving. Factors that increase the risk of exposure to body fluids Failure to adopt universal precautions. Not following established a protocol of safety. Performing high-risk procedures that increase the risk of blood exposure such as withdrawing blood, working in the dialysis unit, administering blood. Using needles and other sharp devices that lack safety features. In reality, almost any microorganism can be transmitted following a needlestick injury, but practically only a handful of organisms are of clinical concern. The most important organisms that can be acquired after a needlestick injury include HIV, hepatitis B, and hepatitis C. All these three viruses can be acquired by a percutaneous needlestick or splashing of blood on the mucosal surfaces of the body. While HIV primarily affects the immune system, both hepatitis B and C have a predilection for the liver. Tetanus should always be considered when a needlestick injury has occurred, and the patient's vaccination history must be obtained.
众所周知,针刺伤在医疗环境中频繁发生且可能很严重。在北美,数以百万计的医护人员在日常工作中使用针头,因此,针刺伤的风险一直令人担忧。虽然普遍预防措施的引入和具有安全意识的针头设计导致针刺伤有所减少,但仍有相关报告,尽管规模比过去小得多。在20世纪80年代初发现艾滋病毒后不久,人们开始对针刺伤有所认识。然而,如今针刺伤后主要关注的不是艾滋病毒,而是乙型肝炎或丙型肝炎。已经制定了指南来帮助医疗机构管理针刺伤以及何时开始暴露后艾滋病毒预防。疾病控制与预防中心(CDC)开发了一个模型,可帮助医护人员知道何时开始抗逆转录病毒治疗。针刺伤是数百万医护人员面临的职业危害。尽管在过去30年中通用指南降低了针刺伤的风险,但这些伤害仍在发生,尽管发生率低得多。针刺伤风险最高的医护人员是外科医生、急诊室工作人员、实验室专业人员和护士。在医疗保健中使用针头是不可避免的,尽管每家医院都有关于正确处理和丢弃针头以及最新的具有安全意识的针头设计的指南,但针刺伤在外科医生和急诊室人员等医护人员中仍更频繁地发生。在大多数情况下,针刺伤主要是由于医护人员的不安全操作和严重疏忽造成的。现实情况是,通过遵循既定程序,大多数针刺伤是可以预防的。在20世纪80年代初发现艾滋病毒后,针刺伤成为医疗保健领域的突出问题。自采取普遍预防措施以来,针刺伤的数量已大幅下降,但仍在发生,不过数量很少。如今针刺伤后主要的威胁不是艾滋病毒,而是感染乙型肝炎或丙型肝炎。过去,大多数针刺伤发生在从患者身上抽血后重新套上针头的过程中。尽管现在不再推荐这种做法,但有传染病专家指出,不重新套上针头会大大增加负责收集和处理锐器容器的清洁工和搬运工针刺伤的风险。多年来,已有许多清洁工和搬运工被未套上护套的针头刺伤的案例报告。此外,当医护人员忽视政策,将针头直接丢弃在塑料袋而不是锐器容器中时,这更令人担忧。为防止这些伤害,许多医疗机构现在采用了独特的重新套上针头的方法。例如,在手术室,现在有关于护士如何将尖锐器械和针头递给外科医生以及反之亦然的既定规程。另一种避免针刺伤的方法是戴双层手套。增加接触体液风险的因素:未采取普遍预防措施;未遵循既定的安全规程;进行增加血液暴露风险的高风险操作,如抽血、在透析单元工作、输血;使用缺乏安全特性的针头和其他尖锐器械。实际上,几乎任何微生物都可能在针刺伤后传播,但实际上只有少数微生物在临床上值得关注。针刺伤后可能感染的最重要的微生物包括艾滋病毒、乙型肝炎和丙型肝炎。这三种病毒都可通过经皮针刺伤或血液溅到身体的粘膜表面而感染。艾滋病毒主要影响免疫系统,而乙型肝炎和丙型肝炎都易侵犯肝脏。发生针刺伤时应始终考虑破伤风,必须了解患者的疫苗接种史。
