Tramadol does not prolong the effect of ropivacaine 7.5 mg/ml for axillary brachial plexus block

Abstract

The addition of 100 mg of tramadol to 7.5 mg/ml of ropivacaine, for axillary brachial plexus block, does not prolong the duration of motor and sensory block and analgesia.

Tramadol Use for Axillary Brachial Plexus Blockade

“…In our study, the total local anesthetic volume used was 42 mL and, similarly, Kesimci et al [12] used a total of 42 mL of local anesthetic solution during axillary block in their study. Adding adjuvant substance to local anesthetic solution decreases the local anesthetic drug quantity and concentration and by this way decreases the possibility of toxicity and lengthens the block duration, which increases the quality of anesthesia and patient comfort [13].…”

“…Adding adjuvant substance to local anesthetic solution decreases the local anesthetic drug quantity and concentration and by this way decreases the possibility of toxicity and lengthens the block duration, which increases the quality of anesthesia and patient comfort [13]. In brachial plexus blockade, clonidine [13][14][15][16][17], tramadol [7,12,13,[17][18][19][20], opioids [13,14,21], neostigmine [13], dexamethasone [19], and ketamine [22] were used as the adjuvant drugs. There are various controversial results in the literature regarding the use of tramadol as adjuvant in peripheric blocks [14,18].…”

Effect of dexamethasone as an adjuvant with bupivacaine in ultrasound guided single shot supraclavicular brachial plexus block in upper extremity surgeries- a prospective randomized study

“…7 Various adjuvants such as tramadol, neostigmine, clonidine, dexamethasone, etc., were tried to enhance the duration of analgesia in supraclavicular brachial plexus block. [8][9][10] They improve analgesia, reduces systemic side effects and reduce total dose of local anaesthetic required.…”

Eficácia analgésica pós-operatória e ação anestésica adjuvante do cloridrato de tramadol utilizado localmente após exodontias de terceiros molares inferiores impactados

“…O cloridrato de tramadol foi aplicado no interior do alvéolo e na submucosa adjacente ao local da exodontia após o término do procedimento, tempo este em que a ação do anestésico já era plena, com a ligação aos canais iônicos do neurônio aferente em curso, sem possibilidade de o tramadol incrementar tal efeito, pois seus sítios de ligação já estavam ocupados com um agente anestésico local de longa duração de efeitos. Semelhantemente, Kesimci et al (2007) não encontraram efeito prolongador do tramadol sobre o bloqueio sensorial e motor do plexo braquial com ropivacaína e atribuíram a ausência de efeito analgésico ao uso de anestésico local de longa duração, que pode ter mascarado o efeito aditivo do tramadol.…”
