The advancement of laparoscopy and minimal access surgery has greatly influenced the
evolution of anaesthetic techniques. However, postoperative pain intensity may be
significant, with up to 40% of patients unsatisfied by routine analgesia and up to 80%may
require rescue opioids during their hospital stay. Diagnostic gynaecological laparoscopy has
no origin of pain other than the abdominal gas insufflations itself only. Pain relief after
diagnostic laparoscopy, being a day case, is an issue of great practical importance.The aim
of this study is to compare the efficacy of combining both pulmonary recruitment and
intraperitoneal lidocaine versus pulmonary recruitment alone to control post - laparoscopy
shoulder pain regarding severity and frequency
Study Design :
Interventional Prospective Randomized Double-blind Controlled Trial
Methodology This study is a randomized double blinded control trial. It will be conducted at
Kasr-al ainy hospital, faculty of medicine, Cairo university. Approval of ethical committee
and written informed consent will be obtained. 88 female patients, aged 18-45 years , ASA 1
or 2 , scheduled for diagnostic gynaecologic laparoscopy will be included. Females who are
(ASA) ≥ 3, alcoholic, drug abusers, allergic to amide LAs, with pre-existing chronic pain
disorders, or receiving opioids or tranquilizers for > 1 week preoperatively are excluded.
Also if the operation included any interventional procedure or was converted to an open
procedure, or had postoperative complications that could increase postoperative pain, it will
be excluded. Consenting patients will be randomly allocated to either of three study groups :
GPL : Patients will receive pulmonary recruitment maneuver and intraperitoneal lidocaine.
GPS: Patients will receive pulmonary recruitment maneuver and intraperitoneal saline. GC :
Patients will receive passive exsufflation through the port site. The patient will attend at
the pre anaesthetic room 1 hour before the procedure. A 20 Gauge cannula will be inserted
peripherally and the patient will be premedicated with intravenous Midazolam 0.02 mg kg-1,
Ranitidine 50 mg, 10 mg Metoclopramide.
In the operative room, standard monitoring will be applied to the patient. Anaesthesia will
be induced with propofol 2 mg kg-1, Fentanyl 1 mcg kg-1 , Atracurium 0.5 mg kg-1 and the
trachea will be intubated after mask ventilation for 3 minutes. Anaesthesia will be
maintained with IPPV , isoflurane in 100% oxygen and muscular relaxation with atracurium
0.1mg kg-1every 15 minutes. Depth of anaesthesia was adjusted according to clinical signs.
Laparoscopy is done using CO2 as distension medium. The patient will be placed in a
Trendelenburg position in order to provide optimum conditions for laparoscopic view. In
groups GPL and GPS , the investigator prepares syringes 1.75 ml/kg of 0.2% lidocaine (3.5
mg/kg) or the same volume of normal saline, for intraperitoneal administration. This ensures
the surgeon and the anaesthesiologist are blind to the patient's group. The solution to be
instilled will be splashed under the right diaphragmatic area by the surgeon and complete the
procedure. At the end of the procedure, the patient will be placed back from trendelenburg
position. In groups GPL and GPS , a pulmonary recruitment maneuver will be done and consist
of five manual pulmonary inflations with a maximum pressure of 40 cm H2O. The
anesthesiologist hold the fifth positive pressure inflation for approximately 5 seconds. In
group GC CO2 will be removed by passive exsufflation through the port site and gentle
abdominal pressure will be applied to evacuate the residual gas. Residual neuromuscular block
is antagonized with atropine 1.2 mg and neostigmine 2.5 mg and extubation will be done
according to extubation criteria. In the recovery room, patient will be asked about
post-operative pain and it'll be controlled using Meperidine 1 mg kg-1 and given by a nurse
who is unaware of the nature of the intraoperative analgesia. Then, the patient is discharged
to the ward according to the standard criteria. In the ward, patient will be asked to fulfill
a questionnaire at 6, 8 and 10 hours postoperative using the visual analogue score (VAS) of
pain severity. Patients were questioned as to presence of Side effects (nausea, vomiting).
Possible Risk : Pneumothorax , Local anaesthetic toxicity : CNS depression (lightheadedness
and dizziness, difficulty focusing, tinnitus, confusion, and circumoral numbness) ,
excitation ( tremors tonic-clonic convulsions) , respiratory depression and cardiac
dysrhythmias .
