Purpose: This randomized, double-blind study evaluated the effectiveness and limitations of continuous serratus anterior plane block (cSAPB) by comparing the effect of cSAPB to patient-controlled intravenous analgesia (PCIA) on postoperative acute pain after thoracoscopic surgery in adults. Patients and Methods: Sixty-six patients who underwent elective video-assisted thoracoscopic surgery (VATS) were randomly allocated to cSAPB or PCIA groups (n=33 per group) after surgery. For the cSAPB group, patients were treated by an initial does of 20 mL ropivacaine (0.375%), followed by continuous infusion at a rate of 5 mL/h of ropivacaine (0.2%) and a patient-controlled bolus of 5 mL ropivacaine (0.2%). PCIA started with an initial does of 0.03 mu g/kg sufentanil, followed by a basal infusion of 0.03 ttg/kg/h sufentanil and a patient-controlled bolus of 0.03 mu g/kg sufentanil. Visual analog scale (VAS) and other items were examined postoperatively. The area under the curve of VAS-time (AUC(VAS-time)) at rest and on coughing in the first 24 hours postoperatively were primary outcomes. Results: At the first 24 hours postoperatively, patients in the cSAPB group exhibited a smaller AUC(VAS-time) at rest (44.0 +/- 17.1 vs 68.9 +/- 11.8 cm.h, P<0.001) and AUC(VAS-time) on coughing (67.1 +/- 8.8 vs 78.0 +/- 12.5 cm.h,P<0.001) compared with those in the PCIA group. The differences in means of VAS score at rest were more than 1.0 cm between the two groups, however, on coughing they were less than 1.0 cm at each observation point. Additionally, patients in the cSAPB group had a longer time to first patient-controlled bolus (15.8 +/- 7.6 vs 10.6 +/- 8.6 hours, P=0.011). Furthermore, a higher rank of satisfaction was recorded with patients in the cSAPB group. Conclusion: cSAPB using PCA devices might be superior to traditional intravenous continuous analgesia, particularly with an advantage of pain relief at rest following VATS operation. Meanwhile, cSAPB lacks a satisfactory analgesic effect on cough.

Constraining the source, genesis, and evolution of Archaean felsic crust is key to understanding the growth and stabilization of cratons. The Akia Terrane, part of the North Atlantic Craton, West Greenland, is comprised of Meso-to-Neoarchaean orthogneiss, with associated supracrustal rocks. We report zircon U-Pb and Lu-Hf isotope data, and whole-rock geochemistry, from samples of gneiss and supracrustals from the northern Akia Terrane, including from the Finnefjeld Orthogneiss Complex, which has recently been interpreted as an impact structure. Isotope data record two major episodes of continental crust production at ca. 3.2 and 3.0Ga. Minor ca. 2.7 and 2.5Ga magmatic events have more evolved epsilon Hf, interpreted as reworking of existing crust perhapslinked to terrane assembly. Felsic rocks from the Finnefjeld Orthogneiss Complex were derived from the same source at the same time as the surrounding tonalites, but from shallower melting, requiring any bolide-driven melting event to have occurred almost simultaneously alongside the production of the surrounding crust. A simpler alternative has the Finnefjeld Complex and surrounding tonalite representing the coeval genesis of evolved crust over a substantial lithospheric depth. Hafnium isotope data from the two major Mesoarchaean crust-forming episodes record a contribution from older mafic Eoarchaean crust. Invoking the involvement of an Eoarchaean root in the growth of younger Mesoarchaean crust puts important constraints on geodynamic models of the formation of the discrete terranes that ultimately assembled to form Earth's cratons.
