产科护理
方法
- 把产妇放在时间轴上定位:孕周、产程阶段或产后第几天,再判断此时什么是正常的。
- 找出处于危险中的对象:母亲、胎儿或新生儿,或者其中不止一个。
- 把发现与其原因联系起来:减速用 VEAL CHOP,出血用四个 T,产后用 BUBBLE-HE。
- 优先选择改善血流和氧合的措施(侧卧、停用缩宫素、宫底按摩),然后再升级处理。
公式表、每个专题的关键方法步骤和 6 道练习题,完整解答附在最后。
On day 2, a newborn has red blotches with small yellow-white centres on the trunk. The baby is well. What is most likely?
A woman needs an emergency caesarean under general anaesthesia. Why is she given an antacid such as sodium citrate before induction?
一名体重 16 kg 的儿童按 15 mg/kg 处方用药。原液浓度为 50 mg/mL。请抽取剂量:应给多少体积 V?
处方剂量为 640 微克。安瓿浓度为 4 mg/mL。请用 1 mL 注射器抽取剂量:应给多少体积 V?
医嘱要求以 100 mL/h 输液,但没有输液泵。改用滴系数为 60 gtt/mL 的输液器重力滴注。求滴速 R,以每分钟滴数表示。
医嘱要求在 6 小时内输入 1500 mL。4 小时后你发现袋中还剩 560 mL,而输液仍须按时完成。 原来的泵速必须提高百分之多少 Δ?
答案: A · Erythema toxicum
Erythema toxicum is a common, benign rash that appears in the first days and resolves without treatment. A well baby with a typical rash needs only reassurance, but blistering or an unwell baby needs review.
答案: B · To make aspirated stomach contents less acidic
Pregnant women are at high risk of aspirating stomach contents under general anaesthesia. Sodium citrate neutralises gastric acid, reducing the severity of lung injury if aspiration happens.
答案: V = 4.8 mL
抽取剂量:体积 = (处方剂量/药物浓度) × 药物体积。先换算成相同的单位,再检查该体积是否适合注射器,并落在它的某一个刻度上。
在这支 10 mL 的注射器上,每条小刻度线代表 0.2 mL。
答案: V = 0.16 mL
抽取剂量:体积 = (处方剂量/药物浓度) × 药物体积。先换算成相同的单位,再检查该体积是否适合注射器,并落在它的某一个刻度上。
答案: R = 100 gtt/min
Infusion rates: a pump is set in mL/h = volume/time in hours. A gravity drip is counted in drops per minute: gtt/min = volume (mL) × drop factor (gtt/mL)/time (min). The drop factor is printed on the tubing package: macrodrip sets deliver 10, 15 or 20 gtt/mL (blood sets often 10 gtt/mL in the US, 15 in the UK) and microdrip sets 60 gtt/mL. Always use the drop factor the question or package gives.
使用微滴输液器(60 gtt/mL)时,gtt/min 等于 mL/h。
答案: Δ = 12 %
Infusion rates: a pump is set in mL/h = volume/time in hours. A gravity drip is counted in drops per minute: gtt/min = volume (mL) × drop factor (gtt/mL)/time (min). The drop factor is printed on the tubing package: macrodrip sets deliver 10, 15 or 20 gtt/mL (blood sets often 10 gtt/mL in the US, 15 in the UK) and microdrip sets 60 gtt/mL. Always use the drop factor the question or package gives.
许多医院允许在不重开医嘱的情况下进行不超过 25% 的此类调整;请查阅本院规定。
