硬膜外腔加點這個藥鎮痛效果更好

硬膜外阻滯是下肢和下腹部手術常用的麻醉方式之一,硬膜外腔內注射局麻藥來獲得鎮痛效果,是否可以複合注射某種藥物增加鎮痛效果,延長作用時間而又不增加麻醉風險呢?有研究者進行了有益的嘗試,並獲得理想的結果,其研究成果發表在 Anesth Pain Med.雜誌上 2021 Feb 28;11(1):e112880. doi: 10.5812/aapm.112880. PMID: 34221950; PMCID: PMC8241816.

硬膜外腔加點這個藥鎮痛效果更好

右美託咪定聯合羅哌卡因用於骶管阻滯鎮痛的隨機雙盲臨床研究

背景:

骶管阻滯鎮痛是用於下腹手術後鎮痛的常用方法之一,但有其自身的侷限性。

目的:

觀察右美託咪定聯合羅哌卡因用於小兒下腹手術後硬膜外阻滯的鎮痛效果及副作用。

方法:

採用隨機雙盲法,將46例3~6歲兒童隨機分為兩組,在全麻下行下腹手術後進行骶管阻滯鎮痛。

對照組注射0。2%羅哌卡因1ml/kg,DR組注射右美託咪定2μg/kg+0。2%羅哌卡因1ml/kg。

在術後1小時、2小時和6小時評估兩組的:

☝疼痛評分(改良CHEOPS評分)、

✌鎮痛持續時間、

鎮痛藥消耗量(靜脈注射撲熱息痛)、

血流動力學變化和可能的不良反應。

結果:

兩組患者術後1h和2h疼痛評分無顯著性差異(P>0。05)。

而DR組術後第6小時疼痛評分明顯降低,

鎮痛持續時間延長(P=0。001)。

DR組的鎮痛劑用量也較低(P=0。001)。

收縮壓和心率無顯著性差異(P<0。05),舒張壓有顯著性差異(P<0。05),DR組低於R組。

兩組在手術時間、恢復時間和副作用方面無統計學差異(P<0。05)。

結論:

在本研究中,

右美託咪定與羅哌卡因聯合應用於硬膜外阻滯可改善小兒術後鎮痛效果,且無明顯不良反應。

Evaluation of Adding Dexmedetomidine to Ropivacaine in Pediatric Caudal Epidural Block: A Randomized, Double-blinded Clinical Trial

Background: Caudal block is one of the methods of pain management performed following lower abdominal surgery, though having its own limitations。

Objectives: In the present study, the effects and side effects of adding dexmedetomidine to ropivacaine in the caudal epidural block were investigated in children after lower abdominal surgery。

Methods: In this randomized, double-blinded clinical trial, 46 children aged three to six years were divided into two groups to perform a caudal block following lower abdominal surgery under general anesthesia。 The injectable solution contained ropivacaine in the R group (1 mL/kg ropivacaine 0。2%), as the control group, and dexmedetomidine (2 µg/kg) and ropivacaine 0。2% (1 mL/kg) in the DR group。 The pain score (modified CHEOPS score), duration of analgesia, amount of analgesia consumed (i。v。 paracetamol), hemodynamic changes, and possible adverse effects were assessed at one, two, and six hours in both groups。

Results: The pain score at one and two hours showed no significant difference between the two study groups (P > 0。05)。 In the DR group, however, the pain score at the sixth hour was significantly lower, and the duration of analgesia was longer (P = 0。001)。 The amount of analgesic consumption was also lower in the DR group (P = 0。001)。 However, there was no significant difference in systolic blood pressure and heart rate (P < 0。05), in the case of diastolic blood pressure, a significant difference (P < 0。05) was seen (DR group lower than the R group)。 There was no statistically significant difference between the study groups in the duration of surgery, recovery time, and side effects (P < 0。05)。

Conclusions: In the present study, the addition of dexmedetomidine to ropivacaine in the caudal epidural blockade improved postoperative analgesia without significant adverse effects in pediatric patients。
