Lidocaine coinfusion alleviates vascular pain induced by hypertonic saline infusion: a randomized, placebo-controlled trial

Background Hypertonic saline solution has been frequently utilized in clinical practice. However, due to the nonphysiological osmolality, hypertonic saline infusion usually induces local vascular pain. We conducted this study to evaluate the effect of lidocaine coinfusion for alleviating vascular pain induced by hypertonic saline. Methods One hundred and six patients undergoing hypertonic saline volume preloading prior to spinal anesthesia were randomly allocated to two groups of 53 each. Group L received a 1 mg/kg lidocaine bolus followed by infusion of 2 mg/kg/h through the same IV line during hypertonic saline infusion; Group C received a bolus and infusion of normal saline of equivalent volume. Visual analogue scale (VAS) scores of vascular pain were recorded every 4 min. Results The vascular pain severity in Group L was significantly lower than that in Group C for each time slot (P < 0.05). The overall incidence of vascular pain during hypertonic saline infusion in Group L was 48.0%, which was significantly lower than the incidence (79.6%) in Group C (P < 0.05). Conclusion Lidocaine coinfusion could effectively alleviate vascular pain induced by hypertonic saline infusion. Trial registration Chinese Clinical Trial Registry, number: ChiCTR1900023753.

Risk Factors for Gemcitabine-Induced Vascular Pain in Patients With Pancreatic Cancer

Background: Peripheral intravenous injection of gemcitabine often causes vascular pain; however, preventive measures have not yet been established. Objectives: This study focused on identifying predictive factors for gemcitabine-induced vascular pain. Methods: We retrospectively analyzed risk factors for developing vascular pain in patients with pancreatic cancer receiving gemcitabine infusions at our institution. Infusions were divided into groups according to presence or absence of vascular pain symptoms, and variables were compared. Odds ratios for risk factors were calculated using logistic regression analyses. Results: Overall, 272 patients with pancreatic cancer were subjected to 725 gemcitabine infusions, and of these, 18.4% (n = 50) experienced vascular pain. There were significant differences in the gemcitabine dose ( P = 0.025), dose of gemcitabine/body surface area (BSA; P = 0.004), concentration of gemcitabine ( P = 0.025), and hot pack use ( P = 0.011) between the vascular pain and no vascular pain groups. Multivariable analyses indicated that gemcitabine dose/BSA and lack of hot pack use were risk factors for developing vascular pain. Moreover, on administration of a higher dosage (>930 mg/m2), the incidence of vascular pain in patients using a hot pack (6.7%) was significantly lower than that in patients not provided a hot pack (16.2%). Conclusions and Relevance: High gemcitabine dosages and lack of hot pack use were predictive factors for gemcitabine-induced vascular pain in patients with pancreatic cancer. Patients receiving gemcitabine treatment should apply a hot pack to the injection site. Scrupulous clinical attention is required for patients presenting with these risk factors to improve pain management.

Oxaliplatin infusion-related venous pain: prevention by simultaneous intravenous fluids

ObjectiveOxaliplatin is a cytotoxic agent frequently used in the treatment of gastrointestinal cancer patients. A known side effect of oxaliplatin administration via a peripheral vein is infusion-related pain. In this retrospective cohort study we compared the incidence of infusion-related pain in patients treated with oxaliplatin with or without simultaneous fluid infusion (FI) (800 mL glucose 5% in 2 hours).MethodsWe retrospectively defined two cohorts: Patients treated with oxaliplatin and simultaneous intravenous FI and the same number of patients treated without FI.The incidence of infusion-related venous pain was the primary outcome measure. Secondary outcomes included: Incidence of hypersensitivity reactions, infusion time, dose density, number of patients switched to a central venous catheter and incidence of peripheral neuropathy.Results100 patients were included, 50 patients in both groups. Baseline characteristics were comparable, except for age (median 66.8 vs 62.4 years in groups with and without FI; p=0.017), and body mass index (28.0 vs 25.7 kg/m2, respectively; p=0.012). Patients treated with simultaneous FI experienced significantly less vascular pain compared with those without FI (10% vs 78%, respectively; p<0.0001; OR 0.031 (95% CI: 0.01 to 0.098)). No difference was observed in dose density, treatment delay or the need of central venous catheter. Logistic regression analysis showed no confounders affecting the primary outcome. No adverse events of FI were observed.ConclusionConcurrent infusion of 800 mL glucose 5% with peripheral venous administration of oxaliplatin significantly reduces the incidence of infusion-related pain in gastrointestinal cancer patients and is highly feasible and affordable in everyday clinical practice.

The effect of various dilute administration of rocuronium blomide on both vascular pain and pharmacologic onset: A randomized controlled trial

Background Rocuronium bromide (RB) is known to cause vascular pain. Although there have been a few reports that diluted administration causes less vascular pain, there have been no studies investigating diluted administration and the onset time of muscle relaxation. Therefore, we examined the influence of diluted administration of RB on the onset time of muscle relaxation and vascular pain. Methods 51 patients were randomly assigned to three groups: RB stock solution 10 mg/ml (Group 1), two-fold dilution 5 mg/ml (Group 2), or three-fold dilution 3.3 mg/ml (Group 3). After the largest vein of the forearm was secured, anesthesia was induced by propofol and 0.6 mg/kg of RB was administered. The evaluation method devised by Shevchenko et al. was used to evaluate the degree of vascular pain. The time from RB administration until the maximum blocking of T1 by TOF stimulation was measured. Results There was no significant difference in escape behaviors of vascular pain among the three groups, and the onset time of muscle relaxation was significantly slower in Group 3 than in Group 1 (p=0.033). Conclusion Our results suggested that it is unnecessary to dilute RB before administration if a large vein in the forearm is used.
