■由于脊柱穿刺针引起的疼痛通常是焦虑和拒绝的原因。ShotBlocker提供非疼痛的物理刺激,抑制疼痛感知。蒸汽冷却剂喷雾含有氯乙烷蒸气,迅速升高皮肤温度,阻碍有害刺激的传播。本研究比较了ShotBlocker装置和蒸汽冷却剂喷雾剂在减少接受选择性下段剖腹产(LSCS)的primigravida妇女的脊髓针相关疼痛方面的有效性。
■我们招募了144名接受选择性LSCS的primigravida女性,并被随机分配到SB组(ShotBlocker装置牢固地压在皮肤上,并且脊柱针通过其狭缝插入),第V组(在插入脊柱针前在穿刺部位使用蒸汽冷却剂喷雾剂),和C组(脊髓麻醉(SA)前接受局部浸润)。使用10点视觉模拟评分(VAS)和3点Likert量表比较两组的针头相关疼痛和患者满意度。
■SB组3.85(0.74)[3.64,4.07]和V组3.04(0.74)[2.83,3.26]的VAS评分均值(标准差)[95%置信区间(CI)]显著低于C组5.19(0.92)[3.28,3.62])。在李克特量表上,血管冷却剂组的最大患者人数(64.6%)反应令人满意,而在对照组中,大多数参与者(62.5%)回答不满意(P<0.001).
■在接受择期LSCS的primigravida患者中,ShotBlocker和蒸汽冷却剂喷雾剂均可减少SA之前的针刺相关疼痛。然而,与ShotBlocker装置相比,Vapocolorcent喷雾剂更有利于减少与脊髓针相关的疼痛。
UNASSIGNED: Apprehension of pain due to a spinal needle is often a cause of anxiety and refusal. ShotBlocker provides non-painful physical stimulation, inhibiting pain perception. The vapocoolant spray contains ethyl chloride vapours, rapidly raising the skin temperature and hampering the transmission of noxious stimuli. The present study compared the effectiveness of the ShotBlocker device and the vapocoolant spray in reducing spinal needle-associated pain in primigravida women undergoing elective lower-segment caesarean section (LSCS).
UNASSIGNED: We enroled 144 primigravida women undergoing elective LSCS and were randomised to Group SB (the ShotBlocker device was firmly pressed over the skin, and the spinal needle was inserted through its slit), Group V (the vapocoolant spray was applied at the puncture site before spinal needle insertion), and Group C (received local infiltration before spinal anaesthesia (SA)). The groups were compared for needle-associated pain and patient satisfaction using a 10-point visual analogue scale (VAS) and a 3-point Likert scale.
UNASSIGNED: The mean (standard deviation) [95% confidence interval (CI)] VAS scores of Group SB 3.85 (0.74) [3.64, 4.07] and Group V 3.04 (0.74) [2.83, 3.26] were significantly lower than that of Group C 5.19 (0.92) [3.28, 3.62]). On the Likert scale, the maximum number of patients in the vapocoolant group (64.6%) responded satisfactorily, while in the control group, the majority (62.5%) of participants responded dissatisfied (P < 0.001).
UNASSIGNED: Both the ShotBlocker and vapocoolant spray reduce needle puncture-associated pain before SA in primigravida patients undergoing elective LSCS. However, the vapocoolant spray is more beneficial in reducing spinal needle-associated pain than the ShotBlocker device.
