Poorly controlled postoperative pain is strongly associated with the development of chronic pain. We aimed to investigate the effect of topical morphine (in 1 of 3 doses: 5, 10, or 15 mg) on acute and chronic neuropathic pain after modified radical mastectomy for cancer breast. Methods: In this registered clinical trial (ClinicalTrials.gov identifier: NCT02462577), 90 patients were allocated to receive 10 mL plain bupivacaine 0.5% plus either 5, 10, or 15 mg morphine (designated by the group namesMorphine5,Morphine10, andMorphine15, respectively). The combination was diluted by saline 0.9% to 20 mL and irrigated in the wound before skin closure. Groups were compared for the following: time to first postoperative analgesia; intravenous patient-controlled analgesia (PCA) morphine consumption; pain scores; hemodynamics; sedation; adverse events in first postoperative 48 hours; and Leeds Assessment of Neuropathic Symptoms and Signs scores in first and third postoperative months. Results: No patient in theMorphine15 group requested postoperative PCA morphine versus 19 and 8 in the Morphine5 andMorphine10 groups, respectively (P 0.002). Time to first analgesic request and total consumption of PCA morphine analgesia were 7.31 ± 3.12 hours versus 14.00 ± 3.54 hours (P 0.000) and 1.42 ± 0.50 mg versus 1.00 ± 0.00 mg (P = 0.371) in the Morphine5 and Morphine10 groups, respectively. Lowest scores on visual analog pain scale at rest (P 0.001) and visual analog pain scale during movement (P 0.01) were recorded in the Morphine15 group, followed by Morphine10 then Morphine5 group. Lowest Leeds Assessment of Neuropathic Symptoms and Signs scores were recorded in the Morphine15 group in the first month (1.10 ± 0.37 vs 5.76 ± 3.26 and 4.73 ± 2.87, P 0.0001) and third postoperative month (4.40 ± 1.77 vs 6.33 ± 3.21 and 5.43 ± 2.67, P 0.006) compared with Morphine5 and Morphine10 groups, respectively. No patient in the Morphine15 group developed chronic pain versus 4 and 2 in Morphine5 and Morphine10 groups, respectively. Conclusions: Topicalmorphine controlled acute postmastectomy pain in a dose-dependent manner and reduced the incidence and severity of chronic postmastectomy pain syndrome.

Objective. To compare the analgesic effect of combined intrathecal morphine and dexmedetomidine with either drug alone for postoperative analgesia in patients undergoing major abdominal cancer surgery. Methods. Ninety patients were allocated to receive intrathecal 10mg bupivacaine 0.5% (bupivacaine group, n530), 10mg bupivacaine 0.5% and 0.5mg morphine (Morphine Group, n530), or 10mg bupivacaine 0.5%, 0.5mg morphine and 5 mg dexmedetomidine (morphine-Dex group, n530). The groups were compared with time to first postoperative analgesia, iv patient-controlled analgesia (PCA) morphine consumption, pain scores, hemodynamics, sedation, and adverse events in the first 48h postoperative. Results. The time to first use of morphine PCA was longer in morphine (22.1365.21h, P50.000) and morphine-Dex (23.4664.69h, P50.000) groups compared with bupivacaine group (0.5060.09h). Dexmedetomidine addition increased the duration of intrathecal morphine (ITM) analgesia by 1.33 h (P50.485). Morphine consumption was less in morphine (10.8362.96 mg, P50.000) and morphine- Dex (11.0063.32 mg, P50.000) groups than in bupivacaine group (27.564.30 mg), with a nonsignificant difference between morphine and morphine- Dex groups (P50.375). Morphine and morphine-Dex groups showed lower pain scores (P 0.001). Intraoperative blood pressure and heart rate were lower in morphine and morphine-Dex groups (P 0.05) with no significant difference between groups in postoperative hemodynamics. Patients in bupivacaine group showed a higher incidence of postoperative nausea (P 0.03) and vomiting (P 0.01), while patients in morphine and morphine-Dex groups had a higher incidence of pruritus (P 0.02). Conclusions. Our results do not support improved analgesia with the combination of intrathecal morphine and dexmedetomidine, despite the absence of significant adverse effects.
