The Radical-7 Pulse CO-Oximeter can be useful as a trend monitor in children during surgery even immediately after intravascular volume expanders are administered. However, it is advisable to confirm the baseline hemoglobin level and to consider the influence of tHb level on the bias. In addition, one should be cautious with regard to using SpHb alone when making transfusion decisions.

A perioperative intravenous lidocaine infusion has been reported to decrease postoperative pain. The goal of this study was to evaluate the effectiveness of intravenous lidocaine in reducing postoperative pain for laparoscopic colectomy patients. Fifty-five patients scheduled for an elective laparoscopic colectomy were randomly assigned to 2 groups. Group L received an intravenous bolus injection of lidocaine 1.5 mg/kg before intubation, followed by 2 mg/kg/h continuous infusion during the operation. Group C received the same dosage of saline at the same time. Postoperative pain was assessed at 2, 4, 8, 12, 24, and 48 hours after surgery by using the visual analog scale (VAS). Fentanyl consumption by patient-controlled plus investigator-controlled rescue administration and the total number of button pushes were measured at 2, 4, 8, 12, 24, and 48 hours after surgery. In addition, C-reactive protein (CRP) levels were checked on the operation day and postoperative days 1, 2, 3, and 5. VAS scores were significantly lower in group L than group C until 24 hours after surgery. Fentanyl consumption was lower in group L than group C until 12 hours after surgery. Moreover, additional fentanyl injections and the total number of button pushes appeared to be lower in group L than group C (P , 0.05). The CRP level tended to be lower in group L than group C, especially on postoperative day1 and 2 and appeared to be statistically significant. The satisfaction score was higher in group L than group C (P ¼ 0.024). Intravenous lidocaine infusion during an operation reduces pain after a laparoscopic colectomy.

Ischiofemoral impingement syndrome is an uncommon disorder defined by hip pain caused by the narrowing of the space between the ischial tuberosity and lesser trochanter with associated entrapment of the quadratus femoris muscle. We effectively treated two male patients using ultrasound-guided prolotherapy with polydeoxyribonucleotide sodium mixed with local anesthetics. A 24-year-old male patient with no history of trauma or surgery complained of bilateral hip and groin pain; magnetic resonance imaging demonstrated slight narrowing of the bilateral ischiofemoral spaces with mild enhancement of the left quadratus femoris muscle. A 23-year-old male patient with a history of iliotibial band release and iliopsoas tendon release complained of left hip and groin pain; magnetic resonance imaging revealed swelling of the left quadratus femoris muscle. After the fifth treatment session of prolotherapy, the pain severity score using the visual analog scale was found to be minimal (0-1/10), and follow-up magnetic resonance imaging revealed a slightly decreased enhancement of the quadratus femoris muscle compared with that on previous images. Prolotherapy with polydeoxyribonucleotide sodium was an efficacious treatment for two patients with ischiofemoral impingement syndrome who were not candidates for surgery.

BackgroundThe present study aimed to compare the intravenous bolus effect of oxycodone and fentanyl on hemodynamic response after endotracheal intubation and postoperative pain in patients undergoing closed reduction of nasal bone fracture.MethodsIn this prospective randomized double-blinded study, 64 patients undergoing closed reduction of nasal bone fracture were randomized into one of two groups: the fentanyl group (Group F) or the oxycodone group (Group O). Each drug (fentanyl 2 mcg/kg in Group F and oxycodone 0.2 mg/kg in Group O) was administered prior to the induction of general anesthesia. Hemodynamic changes after endotracheal intubation and postoperative pain were then measured in both groups.ResultsThere was no significant difference in the change in mean arterial pressure and heart rate between pre-induction and post-intubation in both Groups F and O (P > 0.05). Postoperative pain in Group O was milder than that in Group F (P < 0.001); however, time to awakening from the end of operation was shorter in Group F (P = 0.012).ConclusionIn patients undergoing closed reduction of nasal bone fracture, oxycodone attenuates hemodynamic response to endotracheal intubation similar to fentanyl. However, oxycodone is more effective than fentanyl in improving postoperative pain.Trial registrationClinical Research Information Service (Trial registry number: KCT0001153) on 3 July, 2014Electronic supplementary materialThe online version of this article (doi:10.1186/s12871-016-0279-x) contains supplementary material, which is available to authorized users.
